❏Use safety equipment. Always wear eye protection. Safety equipment such as
a dust-mask, non-skid safety shoes, hard hat, and hearing protection used for
appropriate conditions will reduce risk of personal injuries.
❏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.
❏Use ear protectors or ear plugs rated for at least 20 dba to protect your
hearing.
❏Do not start the engine until the machine is in the cutting position next to the
stump.
❏Do not overreach. Keep proper footing and balance at all times. This enables
better control of the stump grinder in unexpected situations.
❏If devices are provided for the collection of dust extraction, ensure that that
these devices are connected and properly used. Use of one of these devices
can reduce dust related hazards.
❏Check stumps to be removed for embedded nails, wire, metal fence posts,
rocks, and other buried impediments which may become dangerously thrown
or cause unexpected machine movements when hit by the cutting wheel.
❏Make sure that all shields and guards are in place and are in good condition
prior to operating the machine. Check the cutting wheel for damage or missing
teeth and replace as necessary.
❏Ensure that everyone in the vicinity is aware of the danger zone associated
with this machine. Any person must avoid the danger zone at all times when
the machine is in operation.

QVTOOLS, LLC |2731 CRIMSON CANYON DRIVE, LAS VEGAS, NV 89128
POWERKING 1-800-344-3371 [e-mail]
❏Make sure that no one is working on, underneath, or close to the machine
before starting the engine or beginning to move the machine. Make sure that
the area is free of personnel.
❏Don’t make alterations or modifications to your stump grinder.
❏Check with your local council and utility providers for the locations of buried
pipes and cables where applicable. Do this before operating the machine.
Fuel Safety
WARNING! Pay attention and use extreme care while handling fuel. Fuel is
extremely flammable and the vapors are highly explosive.
❏Never remove the fuel cap or add fuel with the machine running. Stop the
engine and allow engine and exhaust components to cool before refueling or
storing.
❏Add fuel outdoors in an open area. Do not smoke while adding fuel.
❏Fill your engine with 10w-30 / 10w-40 / 15w-40 engine oil before use or serious
damage will occur.
❏Never refuel or store the machine in a place where there is an open flame,
spark, or other ignition objects.
❏If you spill gasoline, do not attempt to start the engine. Move the machine
away from the area of the spill and avoid creating any source of ignition until
the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire
hazard and properly dispose of the waste.
❏Always make sure the fuel cap is securely tightened and replace before
starting.
❏If the fuel tank needs to be drained, it should be done outdoors.
❏The muffler and engine become very hot and can cause severe burn. Do not
touch.

OPERATIONS
Adding Oil To The Engine
1. Only fill the fuel tank to a level 15mm lower than the top of the fuel tank. Do
not overfill.
2. Use the dipstick to check the oil level. Use 10w-30 engine oil. Fill to the correct
level before use.
3. Both yellow fill plugs go to the same reservoir. Fill with whichever side is
accessible.
NOTE: The engine is shipped without oil. Operating the engine with no oil or oil at a
low level will destroy the engine. This is not covered under warranty.
Starting The Engine
❏Lock the travel wheel by pulling the brake lever back fully.
❏Make sure throttle is in slow position.
❏Make sure emergency stop pull is installed and palm stop switch is reset by
twisting right.
Do not allow the rope to snap back. Set it back by hand to prevent damage to the
starter.
❏If the engine is cold, move the choke lever to the closed position.
❏Raise the cutter wheel 4 to 5 inches off the ground by pushing downwards on
the handle bar and hold it in that position.
This next step may cause the cutter wheel to rotate. Keep everyone away.
❏Pull the starter rope lightly until you feel resistance, then pull briskly.
❏Move the choke lever to the open position.
The next step causes the cutter wheel to rotate. Again, keep everyone away.
❏Move the throttle to fast. If the engine is cold, allow the engine to idle (throttle
set to slow) for a few minutes before cutting.

Removing Stumps
❏Remove all loose pieces of wood, stones, wire and other debris from the area
before beginning stump removal.
❏Wind direction should be considered, as it will influence the direction in which
dust and wood chips are directed.
❏Never operate the grinder after dark. There will be no adequate light for the
operator to use the grinder safely.
❏Always allow a cold engine time to warm up before cutting a stump.
❏Only the portion of cutting wheel within the 80 degree area shown below
should engage the stump. Never undercut the stump or use the bottom of the
cutting wheel for cutting purposes.
❏Never leave controls when the cutting wheel is rotating.
❏Do not angle engine more than 25 degrees while in operation. Doing so can
cause damage to the engine.
Operating Tips!
❖Use smooth and comfortable side to side movements while operating.
❖When you need to cut smaller roots, it may be more effective to do so
before cutting the stump, rather than after.
❖Should the chip build-up become excessive when cutting, shut off the
machine, wait for the cutting wheel to stop rotating, retract the machine

QVTOOLS, LLC |2731 CRIMSON CANYON DRIVE, LAS VEGAS, NV 89128
POWERKING 1-800-344-3371 [e-mail]
from the stump and rake away the chips. It is also possible to use the
cutter wheel to push chips off the the side.
❖In order to prevent any of the wheels becoming stuck in the hole.
Move the grinder to the other side of the stump to continue
removal or by filling the hole with chips before continuing.
You will want to prepare the grinder at the stump by placing it into position
with the cutting wheel near the top edge of the stump. (See image below)
Removing Roots
1. Make sure the throttle is set to fast. The cutter wheel will accelerate to cutting
speed.
2. Swing the cutting wheel to one side, then lower it into the nearest roots that
are buried at the foot of the stump.
3. Swing the cutting wheel before each sweep until the roots are sufficiently
removed.

POWERKING 1-800-344-3371 [e-mail]
Cutting The Full Stump
1. Make sure the throttle is set to fast. The cutter wheel will accelerate to cutting
speed.
2. Direct the cutter wheel against the stump, beginning with the nearest top
corner of the stump. Steadily sweep it across the stump left and right, cutting
away a ½ inch of wood with each sweep.
3. Raise and lower the cutter wheel between sweeps by lowering and raising the
control handle.
4. Roll the machine forward and back by pushing and pulling on the control
handle. To do this, release the brake. Relock it when the machine has been
repositioned and continue cutting.
Continue with the final removal of roots
Cut the remaining roots as described in step 2 until satisfactorily removed.
Shutting Off The Grinder
1. When stopping the machine after normal operation, lower the engine speed to
slow and press the emergency switch.
2. Set park brake before leaving the controls.
3. Shut off the engine by pressing the on/off switch.
Standard Shutdown Procedure
In consideration of your own safety and that of other, you should always use the
following normal shutdown procedures before departing from the controls for any

QVTOOLS, LLC |2731 CRIMSON CANYON DRIVE, LAS VEGAS, NV 89128
POWERKING 1-800-344-3371 [e-mail]
reason including cleaning, servicing, transporting, or inspecting the stump grinder.
Never deviate from this procedure unless instructed in this manual or in an
emergency that requires it.
WARNING! A rotating cutting wheel is very dangerous. Stand at controls and
ensure that the cutting wheel comes to a complete stop before doing anything else.
1. Move the engine throttle to the slow position.
2. Push the emergency (on/off) switch to stop the engine.
3. Set park brake before leaving controls.
Emergency Shutdown Procedure
1. Immediately press the emergency (on/off) switch to stop the engine.

❏Never store the equipment with petrol in the tank inside a building where
fumes can reach an open flame or spark. Allow the engine to cool before
moving the grinder.
❏To reduce fire hazards, keep the engine and petrol storage area free of grass,
dirt, and excessive grease.
❏Replace worn or damaged parts for safety. If the fuel tank has to be drained,
this should be outdoors.
❏Regularly check the oil level and add some oil or replace it if necessary.
❏Frequently check the grinder and ensure that all bark and dirt deposits are
removed from beneath the deck.
❏Lubricate the wheel axle and the bearings with grease regularly.
❏Check the cutting wheel often. In order to achieve clean work, the blade should
always be sharp and well balanced.
❏Check the tightening of all bolts and screws at regular intervals. Nuts and bolts
that are worn out or badly tightened can damage the engine or the frame.
❏If the grinder hits an obstacle violently, stop the grinder and take it to a
specialist for inspection.
Transportation
The stump grinder is designed to be transported via a van or small trailer. The
machine is equipped with grab bars that are to be used for both lifting the machine
and strapping it down. This machine weighs approximately 240lbs (110kg) and
should only be lifted using correct apparatus or an adequate number of people
working as a team.
There are legal road requirements for towing equipment and trailers (such as lighting
and licensing). It is the owners responsibility to be aware of these laws and to adhere
to them.

Cutting Teeth
To ensure prolonged life and reliability, we recommend to torque the cutting teeth
bolts to 60 ft lbs before each use.
Belts
To tension the belts, loosen the 4 bolts that hold the engine to the frame. Turn the
tensioning rod on the back of the unit to slide the engine forwards or backwards to
properly tension the belts. Once tensioned, tighten the bolts. The tension of the belts
should be about 0.5in deflection.
