• Replace damaged cutting wheel before operating.
• Do not fill water compartment above water fill line.
17. Stay alert. Watch what you are doing. Use common
sense. Do not operate a power tool when you are tired.
18. Check for damaged parts. Before using a tool, check
that there are no damaged parts. If a part is slightly
damaged, carefully determine if it will operate properly
and perform its intended function. Check for alignment
of moving parts, binding of moving parts, breakage
of parts, proper mounting and any other conditions
that may affect the operation of the tool. A part that is
damaged should be properly repaired or replaced by an

this Instruction Manual.
• Ensure that the directional arrow marked on the blade
corresponds with the rotational direction of the motor.
• With the machine disconnected from the power supply,
rotate the blade by hand to ensure it is free from
obstruction.
• Always keep the blade-securing nut and flanges clean.
• Ensure that the blade-securing nut is securely tightened
with the wrenches provided.
• Never try to cut freehand. Always ensure that the tile to
be cut is pressed firmly against the rip fence.
Defective switches must be replaced by an authorised
service facility. Do not use a tool if the switch does not
turn the tool on and off correctly.
• Ensure that the piece of tile that will be cut off has
sufficient room to move sideways. Failure to do so may
result in the off cut binding against the blade.
19. Guard against electric shock. Prevent body contact
with grounded objects such as water pipes, radiators,
cookers and refrigerator enclosures.
• Never cut more than one tile at a time.
• Never cut pieces too small to be held securely against
the rip fence without leaving enough space for the hand
to be a safe distance from the blade.
20. Use only approved parts. When servicing, use only
identical replacement parts. Use an authorised service
facility to fit replacement parts.
• Ensure that the table and surrounding area are clear
with the exception of the tile to be cut.
Additional safety rules for tile cutting saws
• Before cutting a piece of tile let the saw blade run freely
for a few seconds. If it makes an unfamiliar sound
or vibrates excessively switch it off immediately and
disconnect from the power supply.
Always connect the machine to a correctly earthed
power supply.
SAFETY SWITCH. The unit is fitted with a 30 mA residual
current circuit breaker (RCD) for extra protection against
electric shock.
• Let the blade reach full speed before starting the cut.
• Let the blade come to a complete stop before removing
any jammed or off cut material from around the blade area.
• For your own safety read instruction manual before
operating saw
• Never allow the blade to run dry. Failure to keep the
water compartment topped up will result in possible over-
heating of the diamond blade and a poor cut in the tile.
• Wear eye protection.
• Use top blade guard for every operation for which it can
be used.
• Disconnect saw before servicing, when changing cutting
wheels, and cleaning.
• Use tool only with smooth edge cutting wheels free of
openings and grooves.

Position of tile saw
Required tools
������������������
1. To avoid the possibility
of the appliance plug or
receptacle getting wet,
position tile saw to one
side of a wall mounted
receptacle to prevent
water from dripping onto
the receptacle or plug. The user should arrange a “drip
loop” in the cord connecting the saw to a receptacle.
The “drip loop” is that part of the cord below the level
of the receptacle, or the connector if an extension cord
is used, to prevent water travelling along the cord and
coming in contact with the receptacle.
A philips head screw driver is required to assemble the
support arms.
�����������������
Unpacking
Due to modern mass production techniques, it is unlikely
that your GMC Power Tool is faulty or that a part is missing.
If you find anything wrong, do not operate the tool until the
parts have been replaced or the fault has been rectified.
Failure to do so could result in serious personal injury.
���������
1. Remove all loose parts from the carton.
2. Remove the packing materials from around the saw.
3. Carefully lift the saw from the carton and place it on a
level work surface.
