UNPACKING Your trimmer has been shipped completely assembled and ready for use. After removing it from the carton, inspect it carefully to make sure no breakage or damage has occurred during shipping. If any parts are damaged or missing, contact your nearest Ryobi dealer to obtain replacement parts before attempting to operate trimmer. A subbase accessory with handles, operator's manual, warranty registration and two wrenches are included in the carton.
FEATURES ON-OFF SWITCH OFF ON OFF ON 1 3/4 1/2 BRUSH CAP DEPTH OF CUT SCALE BASE MOTOR HOUSING WING BOLT WRENCH (2) COLLET NUT COLLET SUBBASE Fig. 2 ADJUSTMENTS WARNING: WARNING: Your laminate trimmer should never be connected to power supply when you are assembling parts, making adjustments, installing or removing cutters, or when not in use. Disconnecting your trimmer will prevent accidental starting that could cause serious injury.
ADJUSTMENTS INSTALLING/REMOVING CUTTERS WRENCH ON COLLET NUT See Figure 3. ■ UNPLUG YOUR TRIMMER. CUTTER WARNING: WRENCH ON SPINDLE FLATS Failure to unplug your trimmer could result in accidental starting causing serious injury. ■ Place your trimmer upside down on a workbench in order to gain easy access to the spindle and collet nut. ■ Place the small end of one of the wrenches provided on the spindle flats. This will hold the spindle stationary.
OPERATION WARNING: Always wear safety goggles or safety glasses with side shields when using your trimmer. Failure to do so could result in dust, shavings, chips, loose particles, or foreign objects being thrown into your eyes resulting in possible serious injury. If the operation is dusty, also wear a face or dust mask. WARNING: When turning your trimmer ON, be prepared for start-up torque. Always have a firm grasp of your trimmer before starting.
OPERATION chips, and a rougher finish. Bigger chips also require more power, which could result in the trimmer motor becoming overloaded. Under extreme force-feeding conditions the relative speed of the cutter can become so slow — and the bites it has to take so large — that chips will be partially knocked off (rather than fully cut off), with resulting splintering and gouging of the workpiece. See Figure 6.
OPERATION DIRECTION OF FEED AND THRUST EXTENSION CORDS TRIMMER FEED DIRECTION TRIMMER FEED DIRECTION TRIM END GRAINS FIRST See Figures 8 and 9. The trimmer motor and cutter revolve in a clockwise direction. This gives the tool a slight tendency to twist (in your hands) in a counterclockwise direction, especially when the motor starts. Because of the extremely high speed of cutter rotation during a “proper feeding” operation, there is very little kickback to contend with under normal conditions.
MAINTENANCE WARNING: BRUSH CAP When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product damage. BRUSH ASSEMBLY BRUSH REPLACEMENT See Figure 10. Your trimmer has externally accessible brush assemblies that should periodically be checked for wear. Proceed as follows when replacement is required: ■ UNPLUG YOUR TRIMMER. WARNING: Failure to unplug your trimmer could result in accidental starting causing serious injury.
ACCESSORIES HELPFUL HINTS EDGE SHAPING WITH OPTIONAL TRIMMER GUIDE ✓ ✓ ✓ ✓ Always clamp workpiece securely before trimming. ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ Keep cutters clean and properly sharpened.
