of hole break-through. Hold the tool firmly and take care when
the bit begins to break through the workpiece.
• Always secure small workpieces in a vice or other hold down
device.
Drilling Wood
When drilling wood the best results will be obtained by using
dedicated wood bits equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the workpiece.

Drilling Metal

When drilling metal the best results will be obtained by using a
dedicated twist drill designed for metal drilling. To prevent the
bit from slipping when starting a hole, make an indentation with
a centre-punch and hammer at the point to be drilled. Place the
point of the bit into the indentation and begin drilling.
Use an appropriate lubricant for the material being drilled with the
exception of iron and brass which should be drilled dry.
Hammer Drilling Operation
Select the hammer drill function on the mode selection switch.
See FIG 2
CAUTION! There is a sudden twisting force exerted on the tool
/ bit at the time of hole break-through, when the hole becomes
clogged with chips and particles, or when striking reinforcing
rods embedded in concrete. Always use the side grip handle
and firmly hold the tool by both the side handle and the switch
handle during hammer drilling operations. Failure to do so
could result in loss of control of the tool and potential injury to
the operator.
Be sure to use a dedicated tungsten-carbide tipped drill bit.
Position the bit at the desired location for the hole, then pull the
switch trigger. Do not force the tool. Consistent light pressure
gives the best results. Keep the tool in position and prevent it
from slipping away from the hole.
Do not apply extra pressure if the hole becomes clogged with
chips or particles. Instead allow the tool to run at idle and then
partially remove the bit from the hole. By repeating this several
times the hole will be cleaned out and normal drilling may be
resumed.
Chiselling Operations
Set the mode selection switch to the preferred operator position,
either chisel (locked) or chisel (unlocked). See FIG 2
CAUTION! When using the tool for chiselling operations it is
very important that the operator wears all the appropriate
safety equipment. Safety glasses and dust masks are essential
and other apparel such as gloves, safety shoes, ear protectors
etc should be worn as necessary.
Ensure that all marking out is completed before any chiselling
is attempted.
Insert the required chisel into the SDS chuck and ensure positive
location. Offer the chisel up to the worksurface and holding
the tool firmly with both hands begin the chiselling operation.
Switch on the tool and begin to cut.
Do not force the tool. Gentle consistent pressure works best. Do not
try to remove too much material in one pass. Several repeat passes
may be needed to achieve the required results.

MAINTENANCE
Note: Any maintenance must be carried out with the machine
switched off and disconnected from the mains/battery power
supply.
Check that all safety features and guards are operating correctly
on a regular basis. Only use this machine if all guards/safety
features are fully operational.
All motor bearings in this machine are lubricated for life.
No further lubrication is required.
Use a clean, slightly damp cloth to clean the plastic parts of the
machine. Do not use solvents or similar products which could
damage the plastic parts.
WARNING! Do not attempt to clean by inserting pointed
objects through openings in the machines casings etc.
The machines air vents should be cleaned using compressed
dry air.
Excessive sparking may indicate the presence of dirt in the
motor or worn out carbon brushes. If this is suspected have the
machine serviced and the brushes replaced at an authorized
service centre.
