RAPID-FEED™ CHIPPER

Troubleshooting Table (continued)

SYMPTOM POSSIBLE CAUSE

The engine lacks

power or is not

running smoothly.

(Please refer to the

Engine Owner’s

Manual for engine-

specific procedures.)

⇒ Check the Throttle Lever travel and adjustment. Is the Throttle Lever

in the Run position?

⇒ Is the Choke lever pushed all the way in to the RUN position? See

Chapter 4.

⇒ Is the air filter clean? If it’s dirty, change it following the procedure in

the Engine Owner’s Manual.

⇒ Are the spark plugs clean? If they are fouled or cracked, change them.

If they are oily, leave them out, hold a rag over the spark plug holes

and engage the electric starter for a few seconds to blow out any oil in

the cylinders, then wipe off the spark plugs and reinsert them.

⇒ Are you using fresh, clean unleaded gas? If it’s old, change it. Use a

fuel stabilizer if you keep gas longer than two weeks or so.

⇒ Does your engine have the right amount of clean oil? If it’s dirty,

change it following the procedure in Chapter 4.

⇒ If your engine still lacks power, contact us at www.DRpower.com or

call 1(800) DR-OWNER (376-9637) for assistance.

Engine smokes.

⇒ Check the oil level and adjust as needed.

⇒ You may be operating the machine on too great an incline. The

machine should be level.

⇒ Check the air filter and clean or replace if needed.

⇒ You may be using the wrong oil - too light for the temperature. Refer

to your Engine Owner’s Manual for detailed information.

⇒ Clean the engine cooling fins and the carburetor housing if they’re

dirty.

⇒ If the engine still smokes, contact us at www.DRpower.com or call

1(800) DR-OWNER (376-9637) for assistance.

Chipping action seems

too slow or flywheel

stalls.

⇒ The engine speed is too slow causing the belt to slip. Run the engine

at full throttle.

⇒ Check for loose or damaged Drive Belts; tighten or replace. See

Chapter 5.

⇒ Check for a dull or damaged Knife; sharpen or replace the Knife. See

Chapter 5.

SHUT DOWN THE ENGINE, WAIT FOR ALL MOVING PARTS TO COME TO A COMPLETE STOP,

REMOVE SPARK PLUG WIRES, DISCONNECT THE NEGATIVE BATTERY CABLE, THEN WAIT 5 MINUTES

BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION ON THE CHIPPER..
