Basic Operation
• Dust and swarf
A correctly fitted dust mask, suitable for activity and in accordance to the relevant standard must be worn.
• Swart produced by metal drilling is sharp. Take precautions when clearing swart. The burr left on the hole is also sharp and
should be removed with a suitable tool.
• Always wear safety goggles.
• Drill bit be hot after use.
Installing And Removing Bits (Fig.4)
Note: This is equipped with an electric brake.
The drill is fitted with a keyless chuck, this means that a chuck key is not required to secure the drill or screwdriver bit.
1. Place drill bit shaft into the chuck as far as possible.
2. Tighten the chuck firmly.
Note: Short screwdriver bits need only to be inserted to the depth off the hexagon shaft before tightening the chuck by hand.
Rotational Drive Selection (Fig.5)
The forward/reverse drive selector switch 7 determines the direction of rotation of drive (clockwise or anticlockwise).
To select the direction of rotation:
Stop machine and push the switch 7 to the left or right.
When the direction switch is pushed to the left, the chuck will rotate clockwise.
When the switch is pushed to the right, the drive rotate anti-clockwise.
Before operation, check that the switch is set the required position. Do not change the direction of rotation until the driver
comes to a complete stop.
When the driver is not in use move the switch to neutral (middle position) in order to lock the trigger.
Note: Failure to use the neutral position may activate the trigger inadvertently. This inadvertent operation may damage the
power tool.
Variable Speed Trigger (Fig.6)
When the trigger 2 is depressed the drive will rotate (provided the direction switch 7 is set in the forward or reverse position).
This trigger switch is electronic which enables the user to vary the speed continuously.
The speed varies according to how far the trigger switch is depressed.
The further it is depressed, the faster the drive spindle will rotate.
The lighter it depressed, the slower it will rotate.
Torque Selection Control (Fig.7)
By turning the collar (9) it is possible to adjust the amount torque.
The 21 available settings provide a facility for setting the torque to the required level. For example, this means that repetitive
driving screws of the same size will be driven into the material to the same torque, thus giving the same fixing strength, or in
the case of countersunk screws, these will all be driven to the same depth in the material.
The torque control prevents the heads of small diameter screws being twisted off when correctly set.
To turn on the drilling function select the drill icon and the hammer icon to turn on the impact function.
Two speed gear box (Fig.8)
Select a low gear 1 (slower rotational speed and higher torque) tor screwdriving.
Use a high gear 2 (faster rotational speed and lower torque) for drilling holes.
Belt Clip (Fig.9)
The spring steel belt clip 6 is convenient for hanging the drill temporarily. The clip can be installed on either side of the tool.
To install the clip:
Locate the clip 6 in position and fasten with screw 6.1 supplied, take care to not over-tighten and strip the thread.
