Before Use

IMPORTANT:

Before first use and after every 6 hours (approx.) of use, fill the gearbox cavity with

gearbox grease. A Pot of Grease (13) is supplied for initial use. See ‘Gearbox Maintenance’ for

application guidance
• Always check that there is sufficient grease in the gearbox cavity before using the drill

Operation

SDS Plus Chuck Operation
Note:

The SDS Plus system allows the bit to move slightly within the chuck when inserted correctly.

The SDS Plus drill or chisel bit does not lock in position like a conventional chuck.
• To fit a bit to the machine, first grease the tail end of the bit. The Pot of Grease (13) supplied is

suitable for this. Pull back the Chuck Protective Cover (2) and hold. Push and rotate the bit into the

SDS Plus Chuck (1), as far as it will go. Release the chuck cover

• The bit should now be locked into the machine. Check by pulling the bit. If the bit can be removed,

repeat the above procedure until the bit is held securely

• To remove a bit from the chuck, pull the Chuck Protective Cover back and hold. The bit can then

be removed from the drill

Note:

The Dust Guard (10) should be used by fitting to the drill or chisel bit to prevent debris and

dust entering the chuck. This is especially important when the drill is used at a raised angle when

working on walls or ceilings. For larger drill or chisel bits it may need to be fitted before the bit is

inserted in the chuck.

Hammer Selection

• The drill can be used in either hammer drill mode (for masonry work) or conventional rotary drill

mode (for wood, metal etc)

• To select hammer drilling mode, rotate the Hammer Selection Switch (6) to the left
• To select rotary drilling mode, rotate the Hammer Selection Switch to the right
• Do not attempt to move the Hammer Selection Switch whilst the drill is running
• Do not attempt to run the drill with the Hammer Selection Switch in a mid position

Rotation Selection

• The drill can be used in either rotation mode (for drilling), or roto-stop mode (for chiselling)
• To select rotation mode, twist the Rotation Selection Switch (3) to the left
• To select roto-stop mode, twist the Rotation Selection Switch to the right
• Do not attempt to move the Rotation Selection Switch whilst the drill is running
• Do not attempt to run the drill with the Rotation Selection Switch in a mid position

Depth Stop

1. To fit the Depth Stop (11) , loosen the Auxiliary Handle (8) by turning the handle grip anti-

clockwise

2.  Lift the Auxiliary Handle up to a horizontal position
3.  Insert the Depth Stop into the Depth Stop Mounting (9) in the Auxiliary Handle
4.  Rotate the handle grip clockwise to re-tighten which will secure the Depth Stop and the Auxiliary

Handle position

Auxiliary Handle

• The Auxiliary Handle (8) should always be used when drilling
• Always hold the drill firmly using both hands
• The Auxiliary Handle position can be adjusted to best suit the work to be performed

On/Off Trigger Switch

• To start the drill, squeeze the On/Off Trigger (5)
• To stop the drill, release the On/Off Trigger (5)

CAUTION:

The drill is not designed to be permanently switched on and there is no lock-on feature.

Do not attempt to improvise such a feature.

WARNING:

This is a single-speed drill without variable speed adjustment. Any drill bit or core drill

that states a maximum rotation speed of less than 800rpm must not be used.

Drilling Concrete

• Using hammer drill mode and rotation mode, apply pressure to the rear of the drill in line with

the drill bit

• For efficient drilling, it is advisable to use TCT (tungsten carbide tipped) drill bits. Ensure that the
