Safety & Operating Instructions
Chapter 3: Operating Your GRAVITY SELF-FEEDING WOOD CHIPPER
This chapter covers the procedures for starting and stopping your new GRAVITY SELF-FEEDING WOOD CHIPPER and
discusses basic
operation features.
•
The design of this machine is for chipping wood. Never use this machine for any other purpose as it could cause serious
injury.
•
Contact with internal rotating parts will cause serious personal injury. Never put hands, face, feet, or clothing into chipper
hopper or discharge opening or near the discharge area at any time.
•
Before performing any maintenance procedure or inspection, shut down the engine, wait for all moving parts to
come to a complete stop (The flywheel will continue rotating for a while after the engine is shut down), disconnect
spark plug wire, keeping it away from the spark plug to prevent accidental starting, disconnect the negative battery
cable, then wait 5 minutes before proceeding.
•
Use only a wooden stick to clear jammed material.
Before Starting the Engine
1.
Check the oil level every time you use the GRAVITY SELF-FEEDING
WOOD CHIPPER. Add oil if needed (see Chapter 2 section “Adding
Engine Oil and Gasoline”.
2.
Check the fuel level. Add fuel as needed (see Chapter 2 section
“Adding
Engine Oil and Gasoline”.
3.
Ensure that the Fuel Shut-Off Valve is in the “ON” position (Figure 23).
4.
Remove any debris buildup from the machine before every use of
the
Chipper.
Note: Check and re-tighten the Drive Belt, if necessary, after an initial break-in
period of one (1) hour (see Chapter 4 “Maintaining the GRAVITY SELF-
FEEDING WOOD CHIPPER
”).
Operation Notes
•
Visually check the Chipper Knife for damage before each use of the
machine. See “VISUAL inspection of the Chipper Knife (before each
use)”
in Chapter 4 for info on accessing the Chipper Knife.
•
At engine start-up, the engine of your MIGHTY MAC CHIPPER operates
under no load
until approximately 1800 RPM, at which speed the
Centrifugal Clutch
engages and begins driving the Rotor Assembly.
Always operate the Engine
at full speed when chipping.
•
Only operate the GRAVITY SELF-FEEDING WOOD CHIPPER from
the Operator Zones
shown (Figure 24).
•
Keep proper balance and footing while operating the GRAVITY SELF-
FEEDING WOOD CHIPPER
.
•
ALWAYS stop the engine when leaving the Operating Zones or
when
moving the machine.
•
Never move the Chipper while the engine is running or the
Flywheel is turning.
