OPERATING INSTRUCTIONS
Removing or installing the bit (Fig. 1 & 2)
Important:
Always be sure that the tool is switched off and
unplugged before removing or installing the bit.
Pull the locator out of the locking sleeve while turning the
locator slightly. Then grasp the bit with a pair of pliers and
pull the bit out of the magnetic bit holder. Sometimes, it
helps to wiggle the bit with the plires as you pull.
To install the bit, push the bit firmly into the magnetic bit
holder. Then install the locator by pushing it firmly onto
the locking sleeve while turning the locator slightly.
Depth adjustment (Fig. 3, 4 & 5)
Adjust the locator by turning the locking sleeve. One full
turn of the locking sleeve moves the locator 2 mm.
Initially, adjust the locator so that the tip of the locator is
flush with the base of the screw head. Drive a trial screw
into your material or a piece of duplicate material. If the
depth is not suitable for the screw, continue adjusting
until the proper depth setting is obtained.
Switch action (Fig. 6)
CAUTION:
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. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
For continuous operation, pull the trigger and then push
in the lock button. To stop the tool from the locked posi-
tion, pull the trigger fully, then release it.
Reversing switch action (Fig. 7)
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the "
position for clockwise rotation or the "
counterclockwise rotation.
CAUTION:
• Always check the direction of rotation before opration.
• Use the reversing switch only after the tool comes to a
complete stop. Charging the direction of rotation before
the tool stops may damage the tool.
Operation (Fig. 8)
Fit the screw on the point of the bit and place the point of
the screw on the surface of the workpiece to be fastened.
Apply presssure to the tool and start it. Withdraw the tool
as soon as the clutch cuts in. Then release the trigger.
CAUTION:
• When fitting the screw onto the point of the bit, be care-
ful not to push in on the screw. If the screw is pushed
in, the clutch will engage and the screw will rotate sud-
denly. This could damage a workpeice or cause an
injury.
• Make sure that the bit is inserted straight in the screw
head, or the screw and/or bit may be damaged.
• Do not continue unnecessary clutching operation.
