OPERATING INSTRUCTIONS
Note:
Before using the tool, read the instruction
book carefully.
1. ON/OFF SWITCH
Depress to start and release to stop your tool.
2. SWITCH LOCK-ON BUTTON
Depress ON/OFF switch (1) then lock-on button (2) (See
Fig 1), release ON/OFF switch first and lock-on button
second. Your switch is now locked on for continuous
use. To switch off your tool just depress and release the
ON/OFF switch.
3. FORWARD AND REVERSE ROTATION CONTROL
For drilling and screw driving use forward rotation
marked “ ” (switch is moved to the left). Only use re-
verse rotation marked “ ” (switch is moved to the right)
to remove screws or release a jammed drill bit (See Fig
3). Never change the direction of rotation when the tool
is rotating, wait until it has stopped.
4. VARIABLE SPEED CONTROL
This tool has a variable speed switch (4) that delivers
higher speeds with increased trigger pressure - speed is
controlled by the amount the switch trigger is depressed
(See Fig 2). Higher speed will produce a higher torque
while a lower speed will produce a lower torque.
5. AUXILIARY (SIDE) HANDLE
To fit the handle (5), slide the handle onto the drill and
rotate to the desired working position. To loosen the side
handle, rotate the handgrip clockwise. To tighten the side
handle, rotate the handgrip counter-clockwise. Always
use the auxiliary handle when you use the tool (See Fig
4).
6. HAMMER ACTION SELECTOR
When drilling masonry and concrete choose the Ham-
mer position . When drilling wood, metal, plastic and
screw driving choose the Drill position (See Fig 5).
7. IMPACT/DRILL LOCKING BUTTON
To change between the hammer and drilling selection
positions you must push the locking button in before ro-
tating the selector to the chosen position, ensuring that
the button springs back out to lock the selector when the
chosen position is reached (See Fig 5).
