The adjustable depth rod is used to drill holes of uniform
depth. Loosen the clamp screw, set to desired position,
then tighten the clamp screw.
Hook

014701
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.
OPERATION
014702
Hammer drilling operation
CAUTION:
•
There is a tremendous and sudden twisting force
exerted on the tool/bit at the time of hole break-
through, when the hole becomes clogged with
chips and particles, or when striking reinforcing
rods embedded in the concrete. Always use the
side grip (auxiliary handle) and firmly hold the tool
by both side grip and switch handle during
operations. Failure to do so may result in the loss
of control of the tool and potentially severe injury.
First, slide the action mode change lever so that it
points to the
marking. The adjusting ring can be
aligned in any torque levels for this operation.
Be sure to use a tungsten-carbide tipped bit.
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position
and prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
Blow-out bulb (optional accessory)
1
002449
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Screwdriving operation
First, slide the action mode change lever so that it
points to the
marking. Adjust the adjusting ring to the
proper torque level for your work. Then proceed as
follows.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
NOTE:
•
Make sure that the driver bit is inserted straight in
the screw head, or the screw and/or bit may be
damaged.
•
When driving wood screw, predrill a pilot hole 2/3
the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
•
If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
