Service And Maintenance; General Power Tool Safety Warnings - Carat DustCatch 230 Operating Instructions Manual

 Vertical slots can easily be grinded by pulling the power tool from
top to bottom.
 At the ending of the grinding procedure swivel the grinding unit
out of the material, when the power tool is still running.
 Switch the power tool off.
 Switch off the laser.
Do not slow down the freewheeling diamond grinding wheel
applying sideward pressure.
The diamond grinding wheel may become very hot while operating.
Don't touch the diamond grinding wheel before it cooled down.
Curved cuts are not possible, the diamond grinding wheel will jam in
the material.
For grinding especially hard material, e.g. concrete with high pebble
content, the diamond grinding wheel can overheat and get damaged.
This is clearly indicated by circular sparking, rotating with the
diamond grinding wheel.
When this occurs interrupt the grinding process and allow the
diamond grinding wheel to cool down. Run the power tool for a short
time at no‐load speed.
Working advice
 Do not strain the power tool so heavily that it comes to a standstill.
 Firmly support the work piece, secured against sliding, e.g. with
clamping devices.
 The power tool may only be used for grinding without the use of
water.
 Noticeable decreasing work progress and circular sparking
indicates the diamond grinding wheel has become dull. Briefly
grinding a abrasive material (e.g. lime‐sand brick) can sharpen the
wheel again.
5. SERVICE & MAINTENANCE
Pull the mains plug of the power tool from the socket, before any
work on the machine itself.
For safe and proper working, always keep the machine and
ventilation slots clean.
Dismount and clean the diamond grinding wheel, spacer and flanges
after finishing. Clean the guard and extraction hood.
Observe the operating instructions of the grinder for supplementary
service and maintenance activities.
Adjusting the laser
The laser must be adjusted to the used grinder. Furthermore it can
occur the laser isn't in line with the diamond grinding wheel any
more. Follow the steps below to adjust the
laser:
 Loosen the knob (A) two revolutions.
 Align the laser by first shifting grip surface
(B) and subsequently twist it in its housing.
 Tighten the knob (A).
Replace the batteries
The laser is powered by batteries. If the laser doesn't light up when
it's switched on, this may be caused by empty batteries. Follow the
steps below to replace the batteries.
Verify the laser is switched off.

 Loosen the three cylindrical screws which mount the cover [7] on
the guard and extraction hood with the aid of a screwdriver.
 Loosen the depth locking [6].
 Remove the cover from the guard and extraction hood.
 Loosen the knob (A), used to adjust the laser.
 Remove the laser unit (B) from the guard and extraction hood.
 Loosen the cap (C) at the back of the laser unit.
 Replace the three empty batteries (D) with three new batteries of
the same type; LR44. Make sure the positive pole of the batteries
are pointing the cap.
Do not dispose of empty batteries in household
waste. Hand them in at an environmentally
compatible recycling facility.
 Tighten the cap on the laser unit.
 Assemble the laser unit in the guard and extraction hood.
 Screw the knob, used to adjust the laser, in the guard and
extraction hood.
 Mount the cover on the guard and extraction hood, mind the inner
guard is swiveled in.
 Tighten the depth locking.
 Tighten the three cylindrical screws in the guard and extraction
hood with the aid of a screwdriver.
 Adjust the laser, see section "Adjusting the laser".
6. SAFETY WARNINGS
GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains‐operated
(corded) power tool or battery‐operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
b) Do not operate power tools in explosive atmospheres, such as in
the presence of flammable liquids, gases or dust. Power tools create
sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug
in any way. Do not use any adapter plugs with earthed(grounded)
power tools. Unmodified plugs and matching outlets will reduce risk
of electric shock.
