GENERAL SAFETY RULES

WARNING! Read and understand all

instructions. Failure to follow all instructions

listed below, may result in electric shock, fire

and / or serious personal injury. The term

“power tool” in all of the warnings listed

below refers to your mains-operated

(corded) power tool.

SAVE THESE INSTRUCTIONS.

Work area safety

Keep your work area clean and well lit.

Cluttered worksites and dark areas invite

accidents.

Do not operate power tools in explosive

atmospheres, such as in the presence of

flammable liquid, gases, or dust. Power tools

create sparks which may ignite the dust or

fumes.

Keep bystanders, children, and visitors away

while operating a power tool. Distractions

can cause you to lose control.

Electrical Safety

Grounded tools must be plugged into an

outlet properly installed and grounded in

accordance with all codes and ordinances.

Never remove the grounding prong or

modify the plug in any way. Do not use any

adaptor plugs. Check with a qualified

electrician if you are in doubt as to whether

the outlet is properly grounded. If the tools

should electrically malfunction or break

down, grounding provides a low resistance

path to carry electricity away from the user.

Avoid body contact with grounded surfaces

such as pipes, radiators, ranges and

refrigerators. There is an increased risk of

electric shock if your body is grounded.

Don’t expose power tools to rain or wet

conditions. Water entering a power tool will

increase the risk of electric shock.

Don’t abuse the cord. Never use the cord to

carry the tools or pull the plug from an outlet.

Keep cord away from heat, oil, sharp edges

or moving parts. Replace damaged cords

immediately. Damaged cords increase the

risk of electric shock.

When operating a power tool outside, use an

outdoor extension cord marked “W-A” or

“W.” These cords are rated for outdoor use

and reduce the risk of electric shock.

Personal Safety

Stay alert, watch what you are doing and use

common sense when operating a power

tool. Do not use tool while tired or under the

influence of drugs, alcohol, or medication. A

moment of inattention while operating

power tools may result in serious personal

injury.

Use safety equipment. Always wear eye

protection. Safety equipment such as dust

mask, non-skid safety shoes, hard hat, or

hearing protection used for appropriate

conditions will reduce personal injuries.

Avoid accidental starting. Be sure switch is

off before plugging in. Plugging in tools that

have the switch on invites accidents.

Remove adjusting keys or switches before

turning the tool on. A wrench or a key that is

left attached to a rotating part of the tool

may result in personal injury.

Do not overreach. Keep a proper footing and

balance at all times. Proper footing and

balance enables better control of the tool in

unexpected situations.

Dress properly. Do not wear loose clothing or

jewelry. Keep your hair, clothing and gloves

away from moving parts. Loose clothes,

jewelry or long hair can be caught in moving

parts.

Tool use and care

Do not force tool. Use the correct tool for

your application. The correct tool will do the

job better and safer at the rate for which it is

designed.

Do not use tool if switch does not turn it on or

off. Any tool that cannot be controlled with

the switch is dangerous and must be

repaired.

Disconnect the plug from the power source

before making any adjustments, changing

accessories, or storing the tool. S uc h

preventive safety measures reduce the risk of

starting the tool accidentally.

Store idle tools out of reach of children and

do not allow persons unfamiliar with the

power tool or these instructions to operate

the power tool. Tools are dangerous in the

hands of untrained users.

Maintain tools with care. Properly maintained

tools are less likely to bind and are easier to

control.

Check for misalignment or binding of moving

parts, breakage of parts, and any other

condition that may affect the tools operation.

If damaged, have the tool serviced before

using. Many accidents are caused by poorly

maintained tools.

Use the power tool, accessories and blades

etc., in accordance with these instructions

and in the manner intended for the particular

type of power tool, taking into account the

working conditions and the work to be

performed. Us e of th e pow er to ol fo r

operations different from those intended

could result in a hazardous situation.

Service

Have your tool serviced by a qualified repair

person using only identical replacement

parts. This will ensure that the safety of the

power tool is maintained.

-WARNING- To reduce the risk of injury, user

must read instruction manual.

from drywall sanding may effect

respiratory function:

Always use a vacuum cleaner with a

bag approved for drywall dust installed.

Always wear a respirator approved for

dust and mist.

3. Sanding LEAD-BASED paint is extremely

toxic and should not be attempted. Only

allow professionals with special training

and equipment perform this task.

4. Maintain proper footing and balance at

all times. Do not overreach. Use proper

scaffolding

5. Always wear appropriate safety

equipment when operating.

c o a s t i n g s a n d i n g h e a d t o s t o p

completely before putting the tool

down.

7. Never operate the tool in an area with

flammable solids, liquids, or gases.

Sparks from the commutator/carbon

brushes could cause a fire or explosion.

8. There are certain applications for which

this tool was designed. T h e

manufacturer strongly recommends that

this tool NOT be modified and/or used

for any application other than for which

i t w a s d e s i g n e d . I f y o u h a v e a n y

questions relative to its application DO

NOT use the tool until you have written

the manufacturer and have been

FUNCTIONAL DESCRIPTION

This Electric Drywall Sander is specially

designed for the most efficient sanding of

drywall or plaster walls and ceilings for both

new construction and renovation work. It is

designed to work in conjunction with a

vacuum cleaner for minimum dust and best

sanding results. The pivoting sanding head

allows excellent results with minimum time

and effort.

Electrical connection

The network voltage must conform to the

voltage indicated on the tool name plate.

Under no circumstances should the tool be

used when the power supply cable is

damaged. A damaged cable must be

replaced immediately by an authorized

Customer Service Center. Do not try to repair

the damaged cable yourself. The use of

damaged power cables can lead to an

electric shock.

Extension cable

If an extension cable is required, it must have

a sufficient cross-section so as to prevent an

excessive drop in voltage or overheating. An

excessive drop in voltage reduces the output

and can lead to failure of the motor. The

following table shows

you the correct cable diameter as a function

of the cable length for this machine. Use only

U.L. and CSA listed extension cables. Never

use two extension cables together. Instead,

use one long one.

● UNPACKING

Carefully remove the tool and all loose items

from the shipping container.

Retain all packing materials until after you

have inspected and satisfactorily operated

the machine.

● CARTON CONTENTS

● To install a sandpaper disc:

1. Unplug the machine.

2. Peel away the worn out sandpaper disc,

leaving the sponge backing pad in

place.

3. Carefully center the new sandpaper

disc and press into place. It will be held

securely by the hook and loop backing.

● To replace the Hook and Loop Sponge Pad:

The sponge pad must be perfectly flat to get

good sanding results. If it is deformed or

damaged it will cause very uneven sanding.

Always replace it when damaged. It is hook

and loop on both sides, so to Replace it, peel

it away from the hook and loop on the

Sanding Plate Base and, taking great care to

keep it perfectly centered, affix a new one.

● The Brush Bristles on the edge of the

Sanding Plate Cover:

The brush bristles on the edge of the Sanding

Plate Cover serve two purposes, they keep

the sanding disc properly aligned with the

work surface without gouging and they also

help the efficiency of the dust collection by

the vacuum cleaner. These brush bristles will

wear with continued use.

The Sanding Plate Cover should be replaced

when the bristles are too worn to ensure

effective dust collection and stabilization of

the sanding head.

To replace the cover, follow these steps:

Hold the sanding plate in one hand and with

the other, using the L-hex wrench (supplied),

first break free the center bolt clockwise (1/8

turn only!).

Then only use the L-hex wrench to hold the

center bolt from turning and spin off the

sanding plate counterclockwise.

Then, press the cover down against the

spring and, using snap-ring pliers, remove the

circlip which holds the sanding plate cover

to the bracket.

Finally, carefully work the vacuum hose free

then lift sanding plate cover away.

Replacement is the opposite of removal.

Don’t forget the spring. Entrust all repairs to

an authorized service center.

● To install the vacuum cleaner hose:

1. Unplug the machine.

2. Plug the vacuum cleaner hose bayonet

mount into the swivel mount in the back

of the machine. Once the tangs of the

bayonet mount are fully inserted in the

slots, hold the swivel mount from turning

and tu rn th e hose ba yon et mou nt

clockwise to lock.

3. Removal is the opposite of assembly.

● The vacuum cleaner:

Ensure that you have a bag installed in your

vacuum cleaner which is approved and

rated for drywall dust.

WARNING: Failure to use an approved dust

bag in your vacuum will increase the level of

airborne dust in the work area. Prolonged

exposure to such dust may cause respiratory

harm.

● STARTING AND STOPPING TOOL

Make sure that the power circuit voltage is

the same as that shown on the specification

plate of the machine and that switch is

“OFF” before connecting the tool to the

power circuit.

● Switching the machine on and off

To switch on:

While holding with the left hand on the

column and the right hand on the main

handle, Press the rocker switch to the right

with the thumb of the right hand. Anticipate

and be ready for the start up torque when

the machine first starts.

To switch off:

Press the rocker switch to the left. After the

machine has been switched off, the sanding

disc will still rotate for a time. Take care that

parts of your body do not come into contact

with the disc and do not set the machine

down while it is still rotating!

● Adjusting the rotation speed:

The speed of the machine is variable to suit

different tasks. It can be adjusted from 650/

min up to 1600/min by using the thumb

wheel. Using the right thumb, turn in the

downward (counterclockwise) direction to

increase the speed and in the upward

(clockwise) direction to decrease the speed.

On/Off Switch

Generally, you should use the higher speed

for fast stock removal and the lower speed

for more precise control.

HOW TO USE THE TOOL

Effective control of this powerful saw requires

two-handed operation for maximum safety

and control.

The proper hold is to keep one hand on the

main handle and the other hand on the

sponge grip on the column. It is vitally

important to keep stable footing at all times,

especially when standing on scaffolding or

stilts.

■ MOUNTING THE OPTIONAL BAIL HANDLE:

1. Loosen the 2 thumb screws (05) and

remove the clamp cap (04).

2. Place the handle in the desired position

on the column.

3. Clamp the handle in place by replacing

the clamp cap and tightening the 2

thumb screws.

● SANDING OPERATIONS

1. Once the machine and vacuum

cleaner are set up and all safety

measures and equipment are in place,

begin by turning on the vacuum cleaner

and then the machine. (If you are using

a vacuum cleaner with integrated

switching, then simply turn the machine

on.)

2. Begin sanding and carefully contact the

work surface as lightly as possible-just

enough to keep the sanding head flat

against the surface.

3. The joints in the sanding head allow the

sanding disc to follow the contours of

the work surface.

4. The best technique is to use overlapping

sweeps and keep the head in constant

motion. Never stop too long in any one

place or there will be swirl marks. With

experience it will be very easy to create

excellent results.

NOTE: Ensure that the sandpaper you are

using is suited to the task. Overly coarse grit

Speed Adjustment

paper may remove material too quickly to

control. While overly fine grit paper may clog

too often and not shape down the surface.

CAUTION: Take care to avoid pointed

projections and nails, etc. This will wipe out

the sandpaper and probably damage the

sponge pad as well.

MAINTENANCE

● KEEP TOOL CLEAN

Periodically blow out all air passages with dry

compressed air. All plastic parts should be

cleaned with a soft damp cloth. NEVER use

solvents to clean plastic parts. They could

possibly dissolve or otherwise damage the

material.

Wear safety glasses while using compressed

air.

Clean the vacuum swivel connector as too

much dust will keep it from turning freely.

● THE CARBON BRUSHES

The carbon brushes are a normal wearing

part and must be replaced when they reach

their wear limit. When the brushes are worn to

a length of 1/4", they should be replaced.

NOTE: Checking and replacing the carbon

brushes should be entrusted to a qualified

service center.

TO CHANGE THE BRUSHES

1. Unplug the machine.

2. Remove the brush cap with a slothead

screwdriver

3. Remove the brush.

4. Install new brushes in reverse order and

replace covers

If the replacement of the power supply

cord is necessary, this has to be done

by the manufacturer or their agent in

order to avoid a safety hazard.
