Adjustable side handle
The drill is supplied with a 360º adjustable side handle (5).
Always fit and use the side handle when using the drill, this
increases safety when operating the drill.
To adjust the side handle, rotate the side handle in an anti
clockwise direction approximately 2 full turns. Once the side
handle is loose rotate the collar left or right to the desired
position. You do not need to fully remove the handle.
If you want to remove the side handle, slide the collar
completely forward over the chuck.
To tighten the collar on the housing, rotate the handle in a
clockwise direction firmly.
Ensure the collar is fully located on the aluminium housing.
Inserting and removing bits
The drill is fitted with auto spindle lock which means if
you try and rotate the chuck by hand the spindle of the
drill will automatically lock. This means you only need to
grasp the chuck and rotate the chuck housing to remove
or fit accessories.
This drill has a keyless chuck, hence a chuck key is not
needed to secure a bit in the drill. Always set the forward/
reverse control (4) to the locked ‘OFF’ position when
installing and removing bits. It is also recommended to
remove the battery pack to avoid unintentional starting.
1. Open the chuck jaws by firmly holding the chuck housing
and rotating the housing in an anti clockwise direction.
Open the jaws sufficiently so as to fit the desired
accessory.
2. Ensure the accessory is fully inserted.
3. To firmly clamp the accessory in the chuck, grasp
the chuck housing and rotate the chuck housing in a
clockwise direction. Ensure the bit is retained firmly or
damage to the chuck jaws can result.
4. To remove the accessory, open the chuck jaws by firmly
holding the chuck housing and rotating the housing in an
anti clockwise direction. Open the jaws sufficiently so as
to remove the specific accessory.
Fitting and removing the battery pack
To remove the battery pack from the drill firmly press the
battery release buttons (6) at either side of the battery pack,
and slide the battery backward out of the tool.
To install the battery pack, align
rails, on the tool with the tabs
on the battery pack and slide
the battery pack on to the drill.
Ensure the battery pack is sitting
straight on the foot and correctly
entering the runners. The battery
should slide fully on to the drill
foot until the battery pack “clicks”
into position.
