Operation Notes • Visually check the Chipper Knife for damage each time you use the machine. NOTE: Check for shaft movement while starting the engine. If the shaft does not turn, clean out the Chipper as instructed on page 24. • At engine start-up, the engine of your DR 13 HP CHIPPER operates under no load until approximately 1200-1400 RPM, at which speed the Centrifugal Clutch engages and begins driving the Rotor Assembly. • Proper Rotor speed is 2400-RPM +/- 200 RPM.
Processing Limbs and Branches • • • • • • ALWAYS WEAR PROTECTIVE GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHILE CHIPPING TO PROTECT YOUR EYES FROM POSSIBLE THROWN DEBRIS. AVOID WEARING LOOSE CLOTHING OR JEWELRY, WHICH MIGHT CATCH ON MOVING PARTS OR THE MATERIAL FED INTO THE CHIPPER HOPPER. WE RECOMMEND WEARING GLOVES WHILE CHIPPING. BE SURE YOUR GLOVES FIT PROPERLY AND DO NOT HAVE LOOSE CUFFS OR DRAWSTRINGS. WEAR SHOES WITH NON-SLIP TREADS WHEN USING YOUR CHIPPER.
Electric-Starting 1. Move the Choke control (Figure 5 on page 19) to the CHOKE position (to the RUN position if the engine is already warm). 2. Move the Throttle to the FAST position (Figure 5 on page 19). 3. Turn the Key (Figure 5 on page 19) to the ON position and then to the START position until the engine starts, then release. The key will snap back to the ON position and the engine will continue to run. 4. As the engine warms up, slowly adjust the Choke to the Run position.
Using the Chipper Hopper The design of the Chipper Hopper mounted on the side of the machine is to chip wood only. The revolving Chipper Knife mounted on a flywheel turns branches fed into the hopper into “chips”. The Chipper can chip twigs and branches ranging in size up to 4-1/2" diameter. Cut your materials into manageable lengths before feeding them into the Chipper Hopper.
