have to be replaced. Check the Service Manual for the order numbers.
i)
All repair work has to be done by qualified Blastrac personnel, this guarantees a safe and reliable
machine.
j)
Always use original Blastrac spare parts, grinding disks and polishing pads. This will ensure the
best performance.
Only original parts meet the factory specifications and quality. Otherwise Blastrac BV cannot guarantee
the safety of the machine.
The part numbers can be found in the Service Manual.
k)
Check the rotating direction of the motor before operation. The correct direction is given with an arrow on
the housing of the motor.
l)

Grinding safety
a)
The machine contains rotating parts, which are protected with a cover. Always leave the diamond disc on
the floor while the motor is turning.
b)
The flexible coupling can become worn out with use, because of this there can be higher vibrations than
normal. Check for this reason the flexible coupling for deformation and damage before every use.
c)
Do not let the machine rest on the diamond disc or coupling when it is not in use, this will cause
deformation to the flexible coupling.
d)
Always put the machine on the machine support/transport wheel which is made especially for this reason.
e)
Make sure the brush seals are in good condition, this to avoid dust escaping.
f)
Make sure the diamond disc is not damaged or worn out.
g)
Always pull out the main plug before u start changing the grinding disks or polishing pads.
h)
When mounting or removing a diamond disc; lay down the machine so it is lying on the handle. Make sure
the machine will not fall back down. A second person can hold the handle down, to make sure it will not
fall back down.
i)
When changing the disks u should wear Personal Protective Equipment like a dust mask, safety goggles,
gloves, protective shoes, and close fitting protective clothing.
Use the vacuum cleaner while changing the discs to prevent excessive dust.
j)
Caution! The grinding disc will heat up during grinding, don’t risk getting burned, always wear
protective gloves when handling them!
k)
The machine contains rotating parts; because of this never pull the machine backwards with a turning
motor.
l)
Be careful with the machine and pull or let down the machine slowly, big shocks can damage the electrical
parts.
3.6
Dustcollector safety
a)
Always use a Blastrac dust collector to ensure a dust-free operation of the machine and clean air at the
workspace. Also the airflow helps to cool the machine and prevents overheating.
b)
When working on or around carcinogenic or pathogenic substances, the dust collector must be fitted
with a HEPA filter.
c)
Read the operating instructions of the dust collector before using it.
d)
The dust container/bag of the dust collector must be emptied regularly. Comply with the local waste
treatment regulations considering the removed material.
e)
The dust hose must be connected properly with a hose clamp and industrial tape.
f)
The dust hose must be undamaged and free of obstructions.
g)
Always switch on the dust collector first!
