throttle position for 2 to 5 minutes before
moving the throttle to the F
AST
position.
Note:
If the outdoor temperature is below
freezing, store the machine in a garage to keep
it warmer and aid in starting.
Driving the Machine
Use the traction controls to move the machine. The
farther you move the traction controls in any direction,
the faster the machine moves in that direction.
Release the traction controls to stop the machine.
CAUTION
When reversing, you may back into stationary
objects or over bystanders and cause serious
personal injury or death.
Look behind you for obstructions or
bystanders and keep your hands on the
reference bar.
The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place the
throttle lever in the F
AST
position for best performance.
You can, however, use the throttle position to operate
at slower speeds.
Shutting off the Engine
1.
Park the machine on a level surface, engage
the parking brake (if applicable), and lower the
grinder.
2.
Move the throttle lever to the S
LOW
position.
3.
If the engine has been working hard or is hot, let
it idle for a minute before turning the key switch
to the O
FF
position.
Note:
This helps to cool the engine before you
shut it off. In an emergency, you can shut off
the engine immediately.
4.
Turn the key switch to the O
FF
position and
remove the key.
CAUTION
A child or untrained bystander could
attempt to operate the machine and be
injured.
Remove the key from the switch when
leaving the machine, even if just for a few
seconds.
Grinding a Stump
1.
Start the engine, raise the grinder, set the
throttle lever to the F
AST
position, and move the
machine to the stump to be ground.
2.
Use the grinder control lever and the traction
control to position the grinder to the side of the
front of the stump, about 2 cm (1 inch) below
the surface (
3.
Start the grinder and wait for it to get up to full
speed.
4.
Use the grinder control lever to swing the grinder
slowly across the face of the stump, cutting
away a swath of chips (
).
Important:
The grinder automatically slows
down the speed at which it swings into the
stump to maintain the optimum flywheel
speed and not bog down in the wood.

5.
Move the machine forward a few centimeters
(inches) and repeat step
(
).
6.
Repeat steps
through
until you have ground
off the entire face of the stump (
7.
Back up the machine, position the grinder to the
side of the front of the stump, and lower it to
about 2 cm (1 inch) below the surface.
8.
Repeat steps
through
until the stump is
ground away.
9.
If there are any large roots to be ground, position
the grinder over each root and use the traction
control and grinder control to move the grinder
along the root, grinding it away.
