GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil and grease, etc.

!WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.

MAINTENANCE

TO RETIGHTEN A LOOSE CHUCK (Figs. 18 and 18a)

The chuck may become loose on the spindle and develop a wobble. Also, the chuck screw may become loose, causing the chuck jaws to bind and prevent them from closing.

To tighten:

1. Lock the trigger switch by placing the

Forward / Reverse Selector Switch with Power

Lock-Off in the center, or OFF position.

CHUCK REMOVAL (Figs. 17, 17a and 17b)

The chuck may be removed and replaced by a new one.

1. Lock the trigger switch by placing the

Forward / Reverse Selector Switch with Power

Lock-Off in center, or OFF position.

2. Insert a 5/16-in. or larger hex key into the jaws

of the chuck and tighten the chuck jaws securely.

3. Tap the hex key sharply with a mallet in a

clockwise direction (see Fig. 17). This will

loosen the screw in the chuck for easy removal.

4. Open the chuck jaws and remove the hex key.

Using a screwdriver, remove the chuck screw

by turning it in a clockwise direction (Fig. 17a).

Note that the chuck screw has left hand threads

tightens.
