Recoil will not pull out
or is difficult to pull.
Remove un-processed material from the Chipper Chute and Shredder Hopper and remove
any built-up debris in the Discharge opening.
There may be an oil compression lock in the cylinder. Take out the Spark Plug; hold a rag
over the Spark Plug hole and pull the Recoil Cord several times to blow out any oil in the
Cylinder. Wipe off the Spark Plug and reinstall it.
Check the Engine oil level; the Engine may be seized.
The Recoil may be broken or jammed. Visit our website at www.DRpower.com.
The Engine will not start
(manual starting).
(Please refer to the
Engine Owner’s Manual
for Engine-specific
procedures.)
Check the oil and gas level.
Make sure that the Fuel Shut-Off is in the ON position.
Check that the Spark Plug Wire is attached.
The Air Filter may be dirty; change it following the procedure in the Engine Owner’s Manual.
The gas may be old; change it if necessary. Use a fuel stabilizer if you keep gas longer than
one month.
Check the Throttle and Choke settings, adjustment and travel.
The Spark Plug may be dirty or cracked; change it if necessary. If it’s oily, leave it out, hold a
rag over the Plug Hole and pull the Recoil Cord several times to blow out any oil in the
Cylinder, then wipe off the Plug and reinsert it. Never use a cracked Spark Plug as serious
damage could result.
If your Engine still won’t start, visit our website at www.DRpower.com.
The Engine will not start
(electric starting).
(Please refer to the
Engine Owner’s Manual
for engine-specific
procedures.)
Check the previous section (manual starting) for possible causes.
Check the wire connections—especially the ground connection, the green wire coming from
the Battery, where it connects to the Engine.
The Battery should be charged. Check the voltage yourself or at a gas station. If it’s low,
charge it with a 12-volt, 1 to 2 Amp trickle charger. If you don’t use your machine for at least
45 minutes at a time, the Battery may need to be periodically charged. See the Battery Care
section in Chapter 4.
If your Battery is charged and your DR still won’t start, visit us at www.DRpower.com or call 1-
800-DR-OWNER (376-9637) for assistance.
Shut down the Engine, remove the Spark Plug Wire, and wait 5 minutes before performing any maintenance procedure or
inspection on the Chipper Shredder.
