Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
Clean the bit shank and apply the bit grease provided

Insert the bit into the tool. Turn the bit and push it in
until it engages. (Fig. 2)
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the
bit again. Turn the bit and push it in until it engages.

After installing, always make sure that the bit is
securely held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the
way and pull the bit out. (Fig. 4)

Side handle (Fig. 10)
CAUTION:
Use the side handle only when chipping, scaling or
demolishing. Do not use it when drilling in concrete,
masonry, etc. The tool cannot be held properly with
this side handle when drilling.
The side handle can be swung 360° on the vertical
and secured at any desired position. It also secures at
eight different positions back and forth on the horizon-
tal. Just loosen the clamp nut to swing the side handle
to a desired position. Then tighten the clamp nut
securely.
Side grip (Fig. 11)
CAUTION:
Always use the side grip to ensure operating safety
when drilling in concrete, masonry, etc.
The side grip swings around to either side, allowing
easy handling of the tool in any position. Loosen the
side grip by turning it counterclockwise, swing it to the
desired position and then tighten it by turning clock-
wise.

Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
''OFF'' position when released.
To start the tool, simply pull the trigger. Release the
trigger to stop.
