Chapter 3: Operating Your Dr Self-Feeding Wood Chipper - DR Pro 475 Safety & Operating Instructions Manual

Chapter 3: Operating Your DR SELF-FEEDING WOOD CHIPPER

•
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 DR 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 24).
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 DR 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 DR SELF-FEEDING WOOD
CHIPPER operates under no load until approximately 1000 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 DR SELF-FEEDING WOOD CHIPPER from the Operator
Zones shown (Figure 25).
•
Keep proper balance and footing while operating the DR 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.
