precautions as outlined in the Engine Manufacturer’s manual
packed separately with your unit. Do not attempt to operate the
machine until you fully understand how to properly operate and
maintain the engine and konw how to avoid accidental injuries
and/or property damage.
If the unit is to be used by someone other than original purchaser,
or is to be loaned, rented, or sold, always provide this manual
and any needed safety training before operation. The user can
prevent and is responsible for accidents or injuries that may occur
to themselves, to other people, or to property.
Do not force the machine beyond its limits. Use the correct
machine for your application.
PERSONAL SAFETY
Do not permit children to operate this machine at any time.
Keep children, pets, and other people not using the unit away
from the work area. Be alert and shut off the unit if anyone enters
work area. Keep children under the watchful care of a responsible
adult.
Do not operate the machine while under the inuence of drugs,
alcohol, or any medication that could affect your ability to use it
properly.
Dress properly: Wear long, heavy pants, work boots, and work
gloves. Do not wear loose clothing, short pants, or jewelry of any
kind. Secure long hair so it is above shoulder level. Keep your
hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
Protect eyes, face, and head from objects that may be thrown
from the unit. Always wear safety goggles or safety glasses with
side shields when operating.
Wear appropriate hearing protection.
Always keep hands and feet away from all moving parts during
operation. Moving parts can cut or crush body parts.
Always keep hands and feet away from all pinch points.
Do not touch parts that might be hot from operation. Allow parts
to cool before attempting to maintain, adjust, or service.
Stay alert, watch what you are doing, and use common sense
when operating the machine.
Do not overreach. Do not operate the machine while barefoot
or when wearing sandals or similar lightweight footwear. Wear
protective footwear that will protect your feet and improve
your footing on slippery surfaces. Keep proper footing and
balance at all times. This enables better control of the machine in
unexpected situations.
INSPECT YOUR MACHINE
Check your machine before starting it. Keep guards in place and
in working order. Make sure all nuts, bolts, etc., are securely
tightened.
Never operate the machine when it is in need of repair or is in
poor mechanical condition. Replace damaged, missing, or failed
parts before using it. Check for fuel leaks. Keep the machine in
safe working condition.
Do not use the machine if the engine’s switch does not turn off
the engine when running. Any gasoline powered machine that
can’t be controlled with the engine switch is dangerous and must
be replaced.
Regularly check to see that keys and adjusting wrenches are
removed from the machine area before starting it. A wrench or
a key that is left attached to a rotating part of the machine may
result in personal injury.
Avoid accidental starting. Be sure the engine’s switch is off before
transporting the machine or performing any maintenance or
service on the unit. Transporting or performing maintenance or
service on a machine with its switch on invites accidents.
If the machine should start to vibrate abnormally, stop the
engine (motor) and check immediately for the cause. Vibration is
generally a warning sign of trouble.
ENGINE SAFETY
This machine is equipped with an internal combustion engine. Do
not use on, or near, forest-covered or brush-covered land unless
the exhaust system is equipped with a spark arrester meeting
applicable local, state, or federal laws.
In the state of California, a spark arrester is required by law.
Other states have similar laws. A spark arrester, if used, must be
maintained in effective working order by the operator.
Never start or run the engine inside a closed area. The exhaust
fumes are dangerous, containing carbon monoxide, an odorless
and deadly gas. Operate this unit only in a well-ventilated
outdoor area.

Safety

SPECIFIC SAFETY RULES
Do not tamper with the engine in an effort to get it to run at
higher speeds. The maximum engine speed is preset by the
manufacturer and is within safety limits. See engine manual.
Keep a Class B fire extinguisher on hand when operating this
machine in dry areas as a precautionary measure.
FUEL SAFETY
Fuel is highly flammable, and its vapors can explode if ignited.
Take precautions when using to reduce the chance of serious
personal injury.
When refilling or draining the fuel tank, use an approved fuel
storage container while in a clean, well-ventilated outdoor area.
While adding fuel or operating the unit, do not smoke, and stay
away from sparks, open ames, or other sources of ignition near
the area of operation. Never ll the fuel tank indoors.
To avoid sparking or arcing, keep grounded conductive objects
– such as tools – away from exposed, live electrical parts and
connections. These events could ignite fumes or vapors.
Always stop the engine and allow it to cool before lling the fuel
tank. Never remove the cap of the fuel tank or add fuel while the
engine is running or when the engine is hot. Do not operate the
machine with known leaks in the fuel system.
Loosen the fuel tank cap slowly to relieve any pressure in the tank.
Never overll the fuel tank. Because engine heat can cause fuel to
expand, never ll the tank to more than 1/2” below the bottom of
the ller neck. This will provide space for fuel expansion.
Replace all fuel tank and container caps securely and wipe up
spilled fuel. Never operate the unit without the fuel cap securely
in place.
Avoid creating a source of ignition for spilled fuel. If fuel is spilled,
do not attempt to start the engine. Instead, move the machine
away from the area of spillage and avoid creating any source of
ignition until fuel vapors have dissipated.
When fuel is spilled on yourself or your clothes, wash your skin
and change clothes immediately.
Store fuel in containers specifically designed and approved for
fuel storage.
Store fuel in a cool, well-ventilated area, safely away from sparks,
open ames, or other sources of ignition.
Never store fuel – or a machine with fuel in the tank – inside a
building where fumes may reach a spark, open ame, or any other
source of ignition (such as a water heater, furnace, or clothes
dryer). Allow the engine to cool before storing in any enclosure.
Thoroughly inspect the area to be worked. Keep the working area
clean and free of debris to prevent tripping. Operate on at, level
ground.
Never place any part of your body where it would be in danger if
movement should occur during assembly, installation, operation,
maintenance, repair, or relocation.
Keep all bystanders, children, and pets at least 75 feet (23m)
away. If you are approached, stop the unit immediately.
Do not mount anything on the hopper and never carry
passengers.
Never park the machine in a place with unstable ground that
could give way, particularly when it is full.
Disengage clutch lever before starting the engine.
Start the engine carefully according to instructions and with feet
away from the moving parts.
Never leave the operating position when the engine is running.
Always hold the unit with both hands when operating. Keep a
firm grip on the handlebars. Be aware that the machine may
unexpectedly bounce upward or jump forward if the machine
should strike buried obstacles such as large rocks or roots.
Walk, never run with the machine.
Do not overload the machine capacity. Always drive at a safe
speed, and adjust the speed to the slope of the land, the surface
conditions of the road, and the weight of the load.
Use extreme caution when in reverse or pulling the machine
towards you.
Exercise extreme caution when operating on or crossing gravel
drives, walks, or roads. Stay alert for hidden hazards or trafc.
On soft ground, drive at the first forward/reverse gear. Do not
rapidly accelerate, turn sharply or stop.
Pay the utmost attention when working on frozen ground, as the
machine may tend to skid.
Do not operate the machine in confined areas where there
may be a risk of crushing the operator between the machine
and another object.
Never operate the machine on slopes where angle is over 20°.
When operating on a slope, whether moving forward or in
reverse, always make certain that the weight is evenly balanced.
Always operate the machine straight up or down slopes, never
drive sideways or across the slope. Do not shift gears on slopes.
When dumping the contents of the hopper, the center of gravity
will change continuously and the ground conditions will be
essential for the stability of the machine. Use extra caution and
control when dumping the hopper on unstable ground, such as
wet clay or soil.

GEAR SELECTION LEVER
The gear selection lever has 4 positions: 3 forward
speeds and 1 reverse. To change speeds, move the
speed shift lever to the desired position. The lever
locks in a notch at each speed selection.
Slower speeds are for heavier loads, while faster
speeds are for transporting light loads or an empty
hopper. It is recommended that you use a slower
speed until you are familiar with the operation of the
power trackbarrow.
If the engine slows down under a load or the tracks
slip, shift the machine into a lower gear.
If the front of the machine rides up, shift the machine
into a lower gear. If the front continues to ride up, lift
up on the handles.
Always release the clutch control lever before changing
speeds. Failure to do so will result in damage to the
power trackbarrow.
Operate the lever to turn left/right.
To raise the hopper, pull the tipping handle upwards
(see Figure 4, Illustration a) until the hopper has
reached the desired position. To stop raising the
hopper, simply release the tipping handle and the
tipping handle will return to its original position.
To lower the hopper, pull the tipping handle down (see
Figure 4, Illustration b) with the right hand. When the
hopper is lowered to the original position, release the
tipping handle back to its original position.

THROTTLE CONTROL
The throttle control regulates the speed of the engine,
and moves between FAST , SLOW , and STOP
positions.
The throttle control will shut off the engine when it is
moved to the STOP position.
CHOKE CONTROL
The choke control is used to choke the carburetor and
assist in starting the engine. The choke control slides
between the CHOKE CLOSED and CHOKE OPEN
positions.
Never use choke to stop engine.
OPERATION
1. Make sure the power trackbarrow is on a at, level surface.
ADD OIL TO ENGINE
3. Using a funnel, add oil up to the FULL mark on the dipstick.
(See engine manual for oil capacity, oil recommendation, and
location of ll cap.)
No oil in the engine originally, but a bottle of engine
oil is in scope of delivery. Don’t start the engine before
adding oil.
Gasoline is highly ammable and explosive. You can
be burned or seriously injured when handling fuel.
Use extreme care when handling gasoline.
Fill the fuel tank outdoors, never indoors. Gasoline
vapors can ignite if they collect inside an enclosure.
Explosion can result.
IMPORTANT: DO NOT OVERFILL!
This equipment and/or its engine may include
evaporative emissions control system components,
required to meet EPA and/or CARB regulations, that
will only function properly when the fuel tank has
been filled to the recommended level. Overfilling
may cause permanent damage to evaporative
emissions control system components. Filling to the
recommended level ensures a vapor gap required to
allow for fuel expansion. Pay close attention while
lling the fuel tank to ensure that the recommended
fuel level inside the tank is not exceeded. Use a
portable gasoline container with an appropriately
sized dispensing spout when lling the tank. Do not
use a funnel or other device that obstructs the view
of the tank lling process.
DO NOT OVERFILL. Check engine oil level daily and
add as needed.
1. The engine must be off and allowed to cool at least two minutes
before adding fuel.
2. Remove the fuel ller cap and ll the tank. (See engine manual
for fuel capacity, fuel recommendation, and location of fuel cap.)
ADD GASOLINE TO ENGINE
2. Remove the oil ll cap/dipstick
to add oil.

If the engine is hot,
closing the choke is not
necessary.
STARTING ENGINE
1. Move the engine switch to the
ON position.
2. Open the fuel shut-off valve.
3. Move the choke lever to the
CLOSED position.
SLOWFAST
OPENCLOSED
ONOFF
ONOFF
Rapid retraction of the starter cord (kickback) will pull
your handand arm toward the engine faster than you
can let go. Broken bones, fractures, bruises, or sprains
could result.
4. Movethethrottle leverslightly
to the FAST speed.
5. Pull the recoil starter until the engine starts. Return the recoil
to the home position after each pull. Repeat the steps as
needed. Once engine has started, set the throttle to the FAST
position before you operate the unit.
SLOWFAST
OPENCLOSED
OPERATING
After the engine warms up, move the throttle lever to accelerate
engine speed.
Engage the required gear and slowly squeeze the clutch control
lever. If the gear does not engage immediately, slowly release the
clutch lever and try again. In this way the power trackbarrow will
start moving.
The power trackbarrow has the steering levers on the handlebars,
which makes steering very easy. To turn right or left, simply pull
the corresponding right or left steering lever.
The sensitivity of the steering increases in proportion to the
speed of the machine and the load. With an empty machine, a
light pressure on the lever is all that is needed to turn. When the
machine is fully loaded, more pressure is required.
The power trackbarrow has a maximum capacity of 1100 LBS.
However, it is advisable to assess the load and adjust it according
to the ground on which the machine will be used.
It is therefore advisable to cover such stretches using low gear and
taking extra care. In such situations, the machine should be kept in
low gear for the whole stretch.
Avoid sharp turns and frequent changes of direction while driving
on rough, hard terrains full of sharp, uneven points with a high
degree of friction.
Even though the unit has rubber tracks, remember to be careful
when working in adverse weather conditions (ice, heavy rain
and snow) or on types of ground that could make the power
trackbarrow unstable.
Please note that as this is a tracked vehicle, it is subject to a
considerable pitching movement when passing over bumps, holes
and steps.
When the clutch control lever is released, the machine will stop
and brake automatically.
If the machine is stopped on a steep slope, a wedge should be
placed against one of the tracks.
IDLE SPEED
Set the throttle control lever to the SLOW position to reduce
stress on the engine when work is not being performed. Lowering
the engine speed will help extend the life of the engine, as well as
conserve fuel and reduce noise level.
STOP ENGINE
To stop the engine in an emergency, simply turn the engine switch
to the OFF position. Under normal conditions, use the following
procedure:
1. Move the throttle lever to the SLOW ( ) position.
2. Let the engine idle for one or two minutes.
3. Turn the engine switch to the OFF position.
4. Turn the fuel valve lever to the OFF ( ) position.
Do not move the choke control to CLOSE to stop the
engine. Backre or engine damage may occur.
Sudden stopping at a high speed under a heavy load
is not recommended. Engine damage may result.

Never use a “pressure washer” to clean your unit.
Water can penetrate tight areas of the machine and
its transmission case and cause damage to spindles,
gears, bearings, or the engine. The use of pressure
washers will result in shortened life and reduce
serviceability.
GEARBOX
The gearbox was lled with lubricant to the proper level at the
factory. Unless there is evidence of leakage or service has been
performed on the gearbox, no additional lubricant should be
required. If lubricant is required, use GL-5 or GL-6, SAE85-95, EP
gear oil lubricant. Do not use synthetic oil.
GENERAL LUBRICATION
Lightly lubricate all moving parts of the machine at the end of the
season or every 25 operating hours.
ADJUSTING CLUTCH
When the clutch begins to show wear, the handle
reach will become wider, making it more difcult to
reach. Follow these steps to return the clutch lever
back to its original position.
ADJUSTING STEERING
If steering becomes difcult to engage follow these
steps to adjust the cable tension.
1. Loosen the jam nut by turning it counter clockwise
with 10mm wrench. (see Figure 6a, Illustration 1)
2. Tighten or loosen the cable by turning the cable
adjustment nut clockwise or counter clockwise with
10mm wrench until you have reached your required
tightness. (see Figure 6a, Illustration 2)
3. Once tightness is set, return the jam nut against
the handle to hold the cable in place. (see Figure 6a,
Illustration 3)
MAINTENANCE
Maintaining your YARDMAX power trackbarrow will ensure long
life to the machine and its components.
PREVENTIVE MAINTENANCE
1. Turn off the engine and disengage all command levers. The
engine must be cool.
2. Keep the engine’s throttle lever in its SLOW position and
remove the spark plug wire from the spark plug and secure.
3. Inspect the general condition of the power trackbarrow. Check
for loose screws, misalignment or binding of moving parts,
cracked or broken parts, and any other condition that may
affect its safe operation.
4. Use a soft brush, vacuum or compressed air to remove all
contaminants from the machine. Then use high quality light oil
to lubricate all moving parts.

LUBRICATION
The gearbox is pre-lubricated and sealed at the
factory. No need to lubricate until 50 hours use.
After rst 50 hours use, change all the transmission
oil. Capacity is 1.5L.
For future use, just check the oil level every 50 hours
of working. If remove the drain plug, no oil ow out,
then add the oil.
Use portable tool lithium #0 grease such as Lubriplate
6300AA , Lubriplate GR-132, or Multifak, e.g. EP-O.
Transmission oil must be replace when engine is
stopped and warm by unscrewing ller cap and drain
plug. When oil is completely drained, replace ller cap
and ll up with fresh oil. (See Figure 8)

TIGHTENING TRACKS
With use, tracks tend to loosen. When operating with loose tracks,
they tend to slip over the driving wheel causing it to jump its
housing, thus damaging wear to the housing.
To check track tightness, proceed as follows.
1. Set the machine on a at surface with compact ground, or on
asphalt or pavement.
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”
off the ground.
3. Measure the track midline vs. the horizontal line. The reading
must not be more than 0,4”~0,6”.
If the distance is greater, proceed as follows.
1. Use the tipping handle to tip the hopper and set it on blocks or
supports rated for the weight of the box.
2. Loosen locknut A.
3. Tighten bolt B until the correct tightness is restored.
4. Secure bolt B by tightening locknut A thoroughly.
5. Return the hopper to its original position.

Figure 10b
Caution: Do not over-tighten your track. The adjustment
of the track and the brakes are linked. The braking
power will lessen the more the track is tightened.

If the adjustment bolt has no more adjustment left,
the tracks may have to be replaced.
0.4” ~ 0.6”
REPLACING TRACKS
Check the condition of the tracks periodically. If any track is
cracked or frayed, it should be replaced as soon as convenient.
1. Lift up the hopper and insert a support rod for safety purposes.
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”
off the ground. (See Figure 11a)
