DENNIS 27" CYLINDER MOWER MODEL G680

INTRODUCTION

The reliability and quality of performance of the DENNIS G680 depends upon some

simple care maintenance carried out regularly. This manual has been prepared to allow the

user to carry out all such work.

It is advisable to read the instructions carefully. Proper care and attention will enable the

machine to give a continuous, satisfactory, and reliable service.

Failure to carry out regular lubrication and maintenance as outlined in this manual may

render any guarantee or warranty invalid.

In the case of any difficulty, or if further information or advice is required, our Service

Department is always at your call. In the interests of speed and accuracy of information

please quote the serial numbers of the machine and engine when making enquiries.

For the mower, this is to be found on a plate attached to the side frame. The engine

number is stamped on either the crank case or the gear casing facing towards the front of

the machine.

DESCRIPTION

Manufactured with a 27" (68cm) cutting width this mower is powered by a 8 h.p. air

cooled single cylinder four stroke petrol engine ( Kubota ). The rear roller and cutter are

controlled independently via belt clutches operated from the console on the upper handlebar

. A parking brake is fitted for added safety when working on sloping ground.

In the design of the machine, special attention has been given to the importance of easy

service and maintenance with the construction based on a sectional assembly system.

These are the Engine Unit, the Rear Roller Unit, and the Front Roller Unit, each of which

can be readily removed individually from the main Frame Chassis Unit.

IMPORTANT INFORMATION

Please read all the details in this section and familiarize yourself and all machine operators

with the contents.

CONTROLS

All controls with the exception of the choke and starter chord are located on the handlebar

console. Decals indicate the location and operation of each.

SAFETY LEVER

Located on then right hand side of the upper handlebar this L shaped black lever is made

from flattened tubular section. It operates an electrical contactor within the console which

interlocks other functions such as cutter clutch and parking brake. This lever is spring

loaded to return to off position when released.

BALE BAR

Located closest to the operator on the upper handlebar assembly this black lever made from

flattened tubular section goes across the width of the handle and is pivoted on both sides. It

operates, via a spring loaded cable assembly, the roller clutch mechanism which is located

under the guard adjacent to the engine. The lever is designed to engage the safety lever

when it is operated (pushed forward), and releases the safety lever when let go. The spring

returns it to the off position. The machine will move forwards when the bale arm is pushed

G680WG_Instructions.doc

towards the upper handlebar and can be "clamped " under ones hand onto the handlebar for

comfortable operation.

CUTTER CLUTCH

Located on the left hand side of the console with a red lever. Forwards to engage, back to

disengage. The lever is interlocked with the safety lever and the engine will cut out if

engaged without firstly operating the safety lever. The lever operates, via a spring loaded

cable, the cutter clutch mechanism located under the chaincase on the left sideplate.

PARKING BRAKE

Located in the centre of the console as a red lever. Forwards to engage the brake, back to

release. The lever system is interlocked with the safety lever and the engine will cut out if

the safety lever is operated with the parking brake on.

The lever operates, via a cable, a braking mechanism locate under the guard next to the

engine.

THROTTLE

Located on the right hand side of the console as a black lever. Forwards for low revs,

backwards for more. The mechanism is a piano wire type. Do not overstrain.

ON/ OFF SWITCH

Located on the right hand side of the console facing the operator position. This switch

isolates the engine and cuts off the spark. Ensure it is in the ON position before attempting

to start the engine and for added safety put to OFF position when the machine is stopped

for added safety.

OPERATING INSTRUCTIONS

PREPARATION FOR USE

Before commencing ensure the turf is free from stones or other obstructions which may

damage the cutter unit.

Set the height of cut to the required level (see page 9)

Check the engine.

Fill the fuel tank 3/4 full with unleaded petrol.

Always check the oil levels of the machine prior to commencing.

Full details are given in the ENGINE Manual, which accompanies this book.

This should be read carefully before starting the engine.

A daily check is recommended.

(Recommended grade oil is SAE 10-40 Multigrade).

Disengage the cutter clutch. This is a red lever located on the handle bar console on the left

hand side when at the operators position.

Set the throttle control on the handlebars console to the idle position.

G680WG_Instructions.doc

Ensure toggle on /off switch to ON position. This is situated on the right hand side of the

handlebar console facing the operator.

The engine may now be started according to the manufacturer's instructions.

TO COMMENCE CUTTING

Once the engine is running and the choke has been turned off set the throttle to middle

position.

Disengage the PARKING BRAKE , engage the SAFETY LEVER with your right hand

and engage the CUTTER CLUTCH with the left hand. The cutter will commence rotating.

Push the BALEBAR forwards to the handlebar and the machine will move forwards. A

slow engagement is possible to avoid the machine skidding or jolting forwards.

It is possible to hold the BALEBAR against the handlebar with one hand as the balebar

clamps the safety lever in the on position.

When it is required to disengage the roller clutch use your right hand to hold the safety

lever in the on position otherwise the engine will stop if the cutter clutch is still engaged.

Practice with the controls will soon bring confidence in operation.

Accidental release in the case of a fall or slip will automatically stop the machine and, if the

cutter clutch was engaged the engine will stop.

TRANSPORT (disengaging the cutter drive)

To ensure the safety of operator and machine we strongly recommend disengaging the

cutter drive when transporting under power between sites.

ENGINE INFORMATION

stroke, forced air cooled engine. For full specifications please refer to the manufacturers

instruction manual included.

Starting the engine:

Once the preparatory steps have been completed as outlined on page 5 the engine may be

started. (see manufacturer operating manual for full details).

Switch on the fuel tap.

Switch the handlebar console cut off switch to ON.

Set the throttle control to a half open position.

Shift the choke lever to the appropriate position (Kubota engine set to

START :

The choke is not required if the engine is warm or the air temperature high.

Grasp the recoil start handle until resistance is felt, then pull it with force.

Do not allow the starter grip to snap back against the engine. Return it gently

to prevent damage to the starter.

G680WG_Instructions.doc

minutes is recommended.

Stopping the engine:

Close the fuel tap.

ENGINE MAINTENANCE (See manufacturer instructions for full maintenance

details)

Check oil level Daily

Change engine oil After 50 working hours (Initial change after 20 hours)

Clean spark plug Every 100 hours

Clean air filter Every 50 hours

Overhaul Every 500 hours

GENERAL ADJUSTMENTS

The DENNIS G680 is supplied with a tool wallet containing set spanners and a plug

spanner. Sizes for adjustment are quoted in mm.

SHEAR BLADE ADJUSTMENT.

Correct setting of the shear blade is essential to effective cutting of grass. If the set is too

far away it will result in bruised grass and poor results. If set too hard on it will cause

excessive wear on the drive system and "dull’ the bottom blade and cylinder because of

heat build up. Never operate the cylinder for more than a few seconds without cutting

grass. Never attempt any adjustment or maintenance whilst the engine is running.

Beware – Cylinders and bottom blades are sharp, wear gloves to protect your hands and

fingers.

The cylinder cassette is set in situ in the machine. We strongly recommend that the spark

plug lead is removed for added safety. Switch off the fuel before tipping machine back to

avoid any chance of spillage.

The adjustment is facilitated by turning the spring loaded bolts on either side of the cutter

cylinder in the direction indicated by the decals. The shear blade carrier is pivoted in the

sideplate and as the "ear " is moved back the blade gets closer to the cylinder. Adjust until

both sides are just in contact with the cylinder. Do not tighten one side excessively as this

will cause twist in the bottom blade.

G680WG_Instructions.doc

The cutting cylinder should just brush against the shear blade. The correct setting is an

audible whisper of cylinder moving against the shear blade -we suggest gloves be worn for

this part of the operation. The unit should just cut 80 g.s.m. (photocopy paper) along its

length. Heavy contact of the blade and cylinder will result in rapid wear.

SETTING FOR HEIGHT OF CUT

Always stop the engine before adjusting the height of cut. Failure to do this may result in

severe injury.
