Hard pad - Heavy sanding on flat surfaces, especially with coarser abrasives. To change backing pad, hold pad firmly and turn screw counterclockwise with 5mm allen wrench provided. Remove old pad, and place new pad over locating pins on drive spindle. Replace screw and securely tighten in a clockwise direction with the allen wrench. Damaged or worn backing pads must be replaced immediately (Fig. 1). BACKING PAD DAMPER Your tool is equipped with an integrated backing pad damper ring. This damper reduces the no-load speed, which helps prevent accidental marking of the workpiece surface and provides uniform finishing. NOTE: If you notice steadily increasing no- load speed, this indicates that the damper ring is worn and needs to be replaced. INSTALLING ACCESSORIES The random orbit sander uses hook-and-loop backed accessories, which firmly grip the pad when applied with moderate pressure. To change the accessory, merely peel off the old accessory, remove dust from the pad if necessary, and press the new accessory in place. Be sure to align the sanding disc holes with the holes in the backing pad to allow the dust extraction system to function. After considerable service the pad surface will become worn, and the pad must be replaced when it no longer offers a firm grip. If you are experiencing premature wearout of the pad facing, decrease the amount of pressure you are applying during operation of the tool. INSTALLING DUST CANISTER To attach dust canister, slide canister support in direction of arrow (A) until it stops. Insert mounting clip into the pocket provided on canister. Then slide canister support through mounting clip in direction of arrow (B) and push onto the dust port. To remove, reverse this procedure. DUST COLLECTION CANISTER The integral dust extraction system collects sanding dust in canister supplied with your sander. For maximum efficiency, the dust canister should be emptied frequently during operation. When the canister is removed from the tool an (optional vacuum hose accessory) can be attached to the dust port. To use this feature, attach vacuum adapter and vacuum hose (optional accessories) to dust port, then connect opposite end of the vacuum hose to a shop vacuum cleaner. CLEANING AND EMPTYING THE DUST CANISTER To empty, lift lid of canister. Knock excess dust out of the micro filter, or remove dust with your fingers or a soft brush. You may notice that all the dust may not come out of the canister. This will not affect sanding performance but will reduce dust collection efficiency. NOTE: Do not wash the micro filter with soap and water. Dust may become more firmly lodged in the pores, which will reduce dust collection, and damage the micro filter. Operating Instructions TRIGGER "ON-OFF" SWITCH To turn the tool "ON" squeeze the trigger switch. To turn the tool "OFF", release the trigger switch, which is spring loaded and will return to the "OFF" position automatically. To increase switch life, do not turn switch on and off while tool is under load. -7 "LOCK-ON" BUTTON The "Lock-ON" button, located near the trigger allows for continuous operation at maximum OPM without holding the trigger. TO LOCK TRIGGER "ON": squeeze trigger, depress button and release trigger. TO UNLOCK THE TRIGGER: squeeze trigger and release it without depressing the "Lock- ON" button. ! WARNING If the “Lock-ON” button is continuously being depressed, the trigger can not be released. VARIABLE SPEED WITH DIAL SETTING Your sander is also equipped with a variable speed dial. The sander's orbital pad speed can be preset from zero to maximum nameplate OPM by rotating the dial in the housing. The dial may be set on or between any of six positions (1=low through 6=high). The "Lock-ON" button may also be used with any setting of the dial. The following table may be used as a general guide for abrasive and backing pad selection, but the best results will be obtained by sanding a test sample of the workpiece first. FRONT HANDLE Your sander is equipped with a removable front handle when sanding in tight quarters. To remove handle, remove screw with allen wrench. Always reinstall handle for normal operation. Depending on the task, you may grip the rear handle alone, the rear handle and the front handle, or the rear handle and the top of the ergonomically contoured soft grip motor housing, which is designed for that purpose.
