1. Introduction

7Blue Diamond® Attachments

2.1 Safety Guidelines

Operating Safety

• Read and follow instructions in this manual

and the machine’s Operator’s Manual before

operating.

• Under no circumstances should young children

be allowed to work with this equipment.

• This equipment is dangerous to persons

unfamiliar with its operation.

• Do not use the cutter if any parts are damaged.

If the oset mower has a defect, immediately

stop using it and remedy the problem before

continuing.

• The safety shield found on the multipurpose

cutter is designed to reduce the risk of

throwin objects; however, the cutter deck

and safety shield cannot prevent all objects

from escaping theblade enclosure in every

mowing conﬁguration, especially when cutting

vertically.

• The cutter can throw objects up to 300 feet. To

avoid serious injury or death, keep all thrown

object shielding in place. Inspect area for

potential thrown objects before cutting.

• DO NOT operate in a work area that has

not been inspected for foreign debris and

obstacles.

• Remove any foreign objects and clearly mark

any objects that cannot be removed.

• Check for overhead and / or underground lines

before operating equipment (if applicable).

• In addition to the design and conﬁguration

of equipment, hazard control and accident

prevention are dependent upon the

awareness, concern, prudence and proper

training of personnel involved in the operation,

transport, maintenance and storage of

equipment.

• Check that the attachment is securely fastened

to the machine.

• Make sure all the machine controls are in the

NEUTRAL before starting the machine.

• Operate the equipment only from the

operator’s position.

• When learning to operate the equipment, do it

at a slow rate in an area clear of bystanders.

• The equipment must be used ONLY on

approved machines.

• DO NOT make any adjustments or repairs on

the equipment while the machine is running.

• DO NOT operate equipment in poor visibility

conditions such as fog, darkness, or any

conditions that limit clear visibility less than

300 feet (100 m) in front of and to the sides of

the equipment.

• When conditions make it necessary to slow

ground speed, shift to a lower gear rather

than reducing engine speed. The engine will

maintain rated speed and keep cutter running

at optimum cutting speed.

• Wear safety glasses, gloves, hearing protection

and other protective clothing when required.

2. Safety

WARNING

Safety precautions and warnings are provided

in this manual and on the unit. If these hazard

warnings are not heeded, bodily injury, or death

could occur to you or to other persons.

Blue Diamond® Attachments8

Personal Protection Equipment

When using this cutter, wear appropriate personal

protective equipment (PPE). This list may include,

but is not limited to:

• Ear Protection

• Hearing Protection

• Protective shoes with slip resistant soles

• Protective goggles, glasses, or face shield

• Protective clothing and gloves

• Safety vest (when operating near roads)

Machine Requirements and Capabilities

• The machine’s operator’s cab should be

equipped with a thermoplastic polycarbonate

or similar material front window, and similar

protection on the sides of the operator’s cab

before operating the equipment.

• The tractor should be equipped with a Roll

Over Protective Structure (ROPS) and a seat

belt. A crushing hazard can ocur if the driver

is ejected from the seat while the tractor is

in motion. Fasten the seat belt whenever the

tractor is moving.

• Keep bystanders clear of moving parts and the

work area. Keep children away.

• Use caution on slopes and near banks and

ditches to prevent overturn.

Fire Prevention Safety

• Flamable debris (leaves, grass, etc.) must

be removed regularly. If ﬂammable debris

is allowed to accumulate, it can cause a ﬁre

hazard. Clean often to avoid this accumulation.

• Carry a ﬁre extinguisher on the tractor at all

times to extinguish possible ﬁres encountered.

• The equipment’s hydraulic motor compartment

must be inspected every day and cleaned

if necessary to prevent ﬁre hazards and

overheating.

• All fuels, most lubricants, and some coolant

mixtures are ﬂammable. Flammable ﬂuids that

are leaking or spilled onto hot surfaces or onto

electrical components can cause a ﬁre.

Hydraulic System

• Check hydraulic tubes, hoses and ﬁttings for

damage and leakage. Never use open ﬂame

or bare skin to check for leaks. Hydraulic tubes

and hoses must be properly routed and have

adequate support and secure clamps. Tighten

or replace any parts that show leakage.

• Always clean ﬂuid spills. Do not use gasoline or

diesel fuel for cleaning parts. Use commercial

nonﬂammable solvents.

2.2 Safety Decals

General Safety Decal Information

Good safety practices require that you familiarize

yourself with the various safety signs, the type

of warning, and the area or particular operation

related to that area that requires your Safety

Awareness.

Pay close attention to the safety signs and

instructional labels attached to the machine and

the cutter. If the cutter is missing a label or a label

has become unreadable, replace the label before

operating the cutter.

Safety Instructions and Instructional

Labels

1. Keep safety signs or instructional labels clean

and legible at all times. Use a clean, damp

cloth to clean safety labels.

2. Replace any missing or hard-to-read safety

signs or instructional labels.

3. Use care when washing or cleaning the

equipment not to remove or damage the

labels. When using a pressure washer to clean

the cutter avoid spraying too close to decals;

high-pressure water can enter through very

small scratches or under edges of decals

causing them to peel or come o.

4. Locations for the labels and replacement part

numbers are shown in the parts section on

page 29.

5. Replacement parts must have replacement

labels attached during installation and/or

before the oset mower is used.

6. Labels are available from your authorized

dealer at no charge.

How to Install Replacement Safey

Decals

1. Clean and dry the installation area.

NOTE: Do not install the signs if the temperature is

below 50°F (10°C).

2. Determine the exact position before you

remove the backing paper.

3. Remove the backing paper.

4. Align the sign over the speciﬁed area and

carefully press the sign to the part/frame.

NOTE: Small air pockets can be pierced with a

pin and smoothed out using the piece of backing

paper.

2. Safety

Blue Diamond® Attachments10

3.1 Work Area Safety

• Never operate the cutter in darkness or foggy

conditions where you cannot clearly see at

least 300 feet in front and to the sides of the

tractor and oset mower.

• Make sure that you can clearly see and identify

passersby, steep slopes, ditches, drop-os,

overhead obstructions, power lines, debris,

and foreign objects. If you are unable to clearly

see these type of items, stop operating the

oset mower.

• Do not operate the multi purpose cutter, or

drive the tractor into material that is burning,

or areas that recently burnt and may contain

hot embers. Burning material, sparks, and

coals could be thrown from the oset mower to

areas of vegetation that might ignite.

• Carry a ﬁre extinguisher on the tractor at all

times to extinguish possible ﬁres encountered.

• Do not operate the multi purpose cutter on a

tractor with an under-frame exhaust.

• Before turning, slightly raise the cutter o the

ground.

• After the cutter is hydraulically disengaged, the

motor can free-wheel for several minutes. Stay

clear of the blades until they come to complete

stop.

• Large, dense, or wet vegetation may need

to be cut in two or more passes to achieve a

uniform cut.

• Stay alert and watch for trees, low hanging

limbs, power lines, and other overhead

obstacles as well as solid ground objects.

• Avoid cutting in reverse.

3.2 Tractor Requirements

The tractor used to operate the oset mower

must have the power capacity to lift, push, and

hydraulically operate the oset mower.

Depending on the model the tractor will need

either:

9 – 14 GPM or oil ﬂow

15 – 20 GPM or oil ﬂow

The recommended tractor is a 3000 pound

tractor with rear ballast (such as a mower deck) to

oset the weight on the front of the tractor. Also

recommended are tractor tires that are “ﬁlled” or

solid to prevent puncture from the brush.

This unit WILL NOT work on a skid steer machine.

Operating the multi purpose cutter with a tractor

that does not meet the following requirements

may cause tractor or oset mower damage and be

a potential danger to the operator and passersby.

Always review the “controls” section of the tractor

operator’s manual to be familiar with the location,

settings, and function of the tractor controls.

Be familiar with all controls before using this

equipment.

• Approved Roll–Over Protective Structure

(ROPS) or ROPS cab and seat belt.

• Tractor Safety Devices; Slow Moving Vehicle

(SMV) emblem, lighting.

3. Operation

WARNING

Always refer to the tractor owner’s manual to

ensure compatibility and maximum safety.

WARNING

Using the cutter on a skid steer will void the

warranty and have potential for serious injury to

the user or bystanders.
