2. Align the holes of the handlebar with the mounting bracket and secure

each with a spring washer, flat washer and an M10x20 bolt. Fasten each

handlebar support onto the engine deck with a spring washer, flat washer

and an M8x25 hex bolt (Fig. 3).

3. Position the bottom panel inside the mounting bracket. Align the holes with

the mounting bracket. Insert a long pin through holes and secure each side

with a flat washer and cotter pin (Fig. 4).

OPERATION

Consult the engine manual for the correct procedure to start and stop

the engine.

1. Start the engine. After the engine warms up, adjust the throttle control (B)

to increase the engine speed.

2. Choose a gear with the gear selection lever (G) and slowly squeeze the

clutch control lever (D) to start moving. If the gear does not engage

straight away, slowly release the clutch lever and try again.

3. The power wheelbarrow has steering levers on the handlebars (C and E).

To turn right, squeeze the right steering lever to slow or stop the track on

that side. The power wheelbarrow will then turn in that direction.

The steering sensitivity increases in proportion to the speed of the

machine. Light pressure on the lever is all that is needed to turn an empty

machine. More pressure is required when the machine is loaded.

4. When the clutch control lever is released, the machine will stop

automatically.

5. Move the Gear Select Lever (G) to neutral.

a. Switch the engine OFF as an additional safety precaution.

6. Dump the load by pulling the tipping handle (H) up to release the dump

box's locking device. Manually raise the dump box to dump the load.

Lower the dump box and the locking mechanism will automatically lock the

box into place. Confirm the dump box is locked into position by attempting

to lift the dump box without using the tipping handle.

DIFFICULT TERRAIN

The power wheelbarrow may be hard to control when carrying a full load on

difficult terrain. The following steps can reduce the chance of losing control of

the equipment.

1. Reduce the power wheelbarrow’s speed to low on difficult terrain such as

soft or frozen ground, on an incline or on loose gravel or stones. This will

allow more time to react to a potential loss of control.

2. Do not allow rapid acceleration, sudden stops or sharp turns. The load’s

momentum can cause the power wheelbarrow to tip or slide in an

unexpected direction.

3. The power wheelbarrow will tilt when the tracks pass over obstacles or

rough terrain.

4. Adverse weather conditions such as wind, rain, snow and ice can make the

power wheelbarrow more difficult to control. Reduce speed and evaluate

the terrain.

a. Rough terrain can wear down the rubber tracks quickly, impairing

their function and reducing their operational life,

5. Place a wedge against one of the tracks if the machine is stopped on a

steep slope.

CARE & MAINTENANCE

1. Maintain the tool with care. A tool in good condition is efficient, easier to

control and will have fewer problems.

2. Inspect the tool components periodically. Repair or replace damaged or

worn components. Only use identical replacement parts when servicing.

3. Follow instructions for lubricating and changing accessories.

4. Keep the tool handles clean, dry and free from oil/grease at all times.

5. Maintain the tool’s labels and name plates. These carry important information.

If unreadable or missing, contact Princess Auto Ltd. for replacements.

WARNING! Only qualified service personnel should repair the tool. An

improperly repaired tool may present a hazard to the user and/or others.

PREVENTIVE MAINTENANCE

Turn off the engine and place the gear selection lever into neutral. Wait until the

engine is cool. Remove all debris and other materials that may have

accumulated on the tracks, engine or chassis.

ADJUSTING THE CLUTCH

A worn clutch may require moving the clutch lever farther before the

clutch engages.

1. Set the clutch lever to its original position.

2. Remove slack from the clutch lever cable with the adjustment device and

counter-nut.

ADJUSTING THE STEERING

The steering system may become less responsive with wear and tear to the unit.

Adjust one steering lever, before adjusting the other one.

1. Loosen the locknut and unscrew the adjuster just enough to allow the

cable to move when force is applied. Do not loosen too much as traction

can be lost.

2. Eliminate slack in the cable and tighten the adjuster.

3. Tighten the locknut and test the tension in the steering lever.

TIGHTEN TRACKS

WARNING! An overtight track will impair the brake’s effectiveness. Test and

adjust the brakes after tightening the track. Replace the track if any

adjustment affects the brakes normal function.

A loose track can slip off the driving wheel. This can cause a hazardous situation or

damage to the equipment. Check the track’s tightness on a regular basis.

1. Set the machine on a flat surface of

asphalt, stone or pavement. Compact

ground is also acceptable.

2. Lift the machine and set it on blocks or

supports rated for the weight of the machine,

so that the tracks are approximately 4 in.

(100 mm) off the ground.

3. Measure the track midline vs. the horizontal

line. The reading must not be more than

10-15 mm. If the distance is greater,

proceed as follows (Fig. 5).

a. Tip the dump box and set it on blocks

or supports capable of holding the weight of the box.

b. Loosen locknut A.

c. Tighten bolt B until the correct tightness is restored to the track.

d. Secure bolt B by retightening locknut A to secure the bolt in place.

e. Return the dump box to its original position.

NOTICE! Replace the track if the guide wheel axle (#81) is fully extended

forward and the track is still too loose.

REPLACING A TRACK

WARNING! Keep hands away from the track and wheels when under power to

avoid a crushing injury.

Check the condition of the tracks periodically. Replace a track that is cracked

or frayed.

1. Set the machine on a flat surface of asphalt, stone or pavement. Compact

ground is also acceptable.

Fig. 5

V 4.1 660 lb Power Wheelbarrow 8724981

Visit www.princessauto.com for more information 11

2. Lift the machine and set it on jack stands or supports rated for the weight

of the machine. The tracks should be 4 in. (100 mm) off the ground.

3. Loosen locknut A and bolt B (Fig. 5) fully to release tension from the track.

4. Pull the track off the toothed drive wheel at the rear by hand if possible. An

alternative is to use a wood block and crowbar to remove the track.

a. Start the engine and shift the power wheelbarrow into reverse.

b. Place a long wood block against the track and drive wheel. The wood

block will lift the track off the drive wheel as it rotates. Place the

power wheelbarrow into neutral gear as soon as the track has lifted.

c. Pull the track towards the side with the crowbar until the track slides

off the wheel. Remove the wood block.

WARNING! Do this carefully to avoid tipping the machine over. The machine

is heavy and can cause a crushing injury.

d. Shut the engine OFF.

e. Pull the track off the other wheels.

5. Place the new track so the teeth

are on either side of the front

wheel. Position the track so it

aligns with the other wheels.

6. Place the track on the rear drive

wheel by hand if possible. Use a

crowbar to slip the track onto the

teeth of the drive wheel.

7. Start the engine and place the

power wheelbarrow in reverse until the drive wheel’s teeth slip into the

slotted holes of the track.

8. Adjust the track tension as explained in the section Tighten Tracks.
