of your bit, decrease the tool performance and shorten the
service life of the tool.
• There is force exerted on the tool / bit at the time 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
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.
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).
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
Maintenance & Troubleshooting
Keep tool, cord, and carry case clean and free from chips.
Avoid using cleaning products, which include benzene,
trichloroethylene, chloride, or ammonia as these can damage
plastic parts. In case of electrical or mechanical malfunction,
immediately switch off the tool and disconnect the plug.
Excessive sparking may indicate the presence of dirt in
the motor or worn out carbon brushes. Check for wear and
replace when they reach 6mm (1/4”). For all other service
take machine to your local dealer, or to Evolution Power
Tools USA, Iowa, if bought in the USA.
Lubrication
Your machine gearbox is lubricated at the factory. To check
and / or add lubricant, it is necessary to dismantle the tool.
This operation should always be handled by the nearest
SERVICE CENTER or Evolution Power Tools USA, Iowa,
if in the USA. All repairs and servicing made by these
centres are fully guaranteed against defective materials and
workmanship.
Notice:
Fair wear and tear and damage caused by misuse is not
covered under the 12-Month guarantee.
ENVIRONMENTAL PROTECTION
Recycle unwanted materials instead of disposing of them
as waste. All tools, hoses and packaging should be sorted,
taken to the local recycling centre and disposed of in an
environmentally safe way.

GETTING STARTED
CAUTION! ALWAYS DISCONNECT THE DRILL FROM

Refer to the “Service Parts List Drawing”.
FUNCTIONAL DESCRIPTION
CAUTION
Always be sure that the tool is switched off and unplugged
before adjusting or checking a function on the tool.
Switch action (FIG1)
CAUTION
• Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the ‘OFF’
position when released.
• The switch can be locked in the ‘ON’ position for ease of
operator comfort during extended use. Apply caution when
locking the tool in the ‘ON’ position and maintain a firm grip
on the tool.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop the drill.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
A speed control screw is provided so that the maximum tool
speed can be limited (variable). Turn the speed control screw
clockwise for higher speed, and counterclockwise for lower
speed.
Reversing switch action
This drill has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the required
position (clockwise or counterclockwise rotation) as indicated
by the arrows on the drill body.
CAUTION
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation before the
tool stops may damage the tool.
Selecting the action mode (FIG2)
This tool has a 4 position action mode selecting switch.
Push in the locking button on the switch lever and rotate the
switch to the desired position. Release the locking button
and ensure that the button has locked the switch in the
required position.
The 4 positions are:
• Drill • Hammer Drill • Chisel (unlocked) • Chisel (locked)
Installing the side handle (FIG3)
CAUTION
Always be sure that the tool is switched off and unplugged
before carrying out any work on the tool.
Always use the side grip handle to ensure operating safety.
Install the side grip handle onto the drill collar and secure in
place by tightening the handle. Note that the handle may be
swung through 360º. Ensure that the side handle is pushed
fully home against the drill body before tightening.
Depth Gauge
The depth gauge is convenient for drilling holes of uniform
depth. To install, loosen the side grip handle and insert the
depth gauge into the hexagonal hole. Adjust to suit and
tighten the side grip handle to lock both the handle and depth
gauge into the desired position.
Installing or removing a drill bit or chisel (FIG4)
CAUTION
Always be sure that the tool is switched off and unplugged
before carrying out any work on the tool.
Carefully insert the SDS chisel or bit into the SDS chuck.
Gently pull the bit into the chuck whilst rotating the bit
slowly. Pull back on the chuck collar and continue pulling the
bit gently until positive location is felt and the bit slides fully
home into the chuck.
Only remove the bit when operations have finished and the
bit has completely cooled down.
To remove the bit, slide the chuck collar rearward and
carefully pull the bit out of the chuck
OPERATION
Standard Drilling Operation
Ensure that the action mode selecting switch is set on the
standard drill mode.
CAUTION
• Using excessive force on the tool will not speed up the
drilling. Excessive pressure will only serve to damage the tip
