INSPECTION, MAINTENANCE, AND CLEANING

1.WARNING! Make sure the Power Switch of the tool is in its “OFF” position and that the tool is unplugged from its electrical outlet before performing any inspection, maintenance, or cleaning procedures.

2.BEFORE EACH USE, inspect the general condition of the tool. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring, and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, have the problem corrected before further use. Do not use damaged equipment.

3.CLEANING: Regularly clean the work surface with a dry brush or clean cloth. Keep moving parts lightly greased. Always keep the Motor and vent areas free of dust and debris.

4.Lubrication: Use the enclosed spanner wrench to unscrew the Seal Cap (18) located on top of the housing. Add the enclosed grease and replace and tighten the Seal Cap.

5.Changing the Carbon Brushes:

a.Using a small standard screwdriver, remove the Brush Covers (81). When you remove the Brush Caps, the Carbon Brush Holder (83) may spring out. Do not lose the Carbon Brushes. If the Brush Holder does not spring out, gently remove it by using the tip of your screwdriver. Examine the surface of each brush. The surface should be smooth and clean. If scratch marks appear, or if the brush is broken, replace the brush immediately with an approved replacement brush from Harbor Freight Tools.

b.If the brush is not damaged but is only dirty, you may clean it off with a pencil eraser. Gently rub with the eraser until the dirt has been removed. Remove any eraser dust which may have accumulated during cleaning.

c.Re-install each Carbon Brush (82) by inserting it back into the Brush Holder (83). Screw the Brush Cover (81) back into the Brush Holder and tighten.
