4 MOUNTING
Mounting the Protective Device
Before you mount the protective devices, insure that
the air tool is not connected to the air supply.
When grinding and cutting off, always use the protec-
tive guard
13
. When sanding, always install the hand
guard
4
on the auxiliary handle
3
. These protective de-
vices are intended to protect you from broken frag-
ments and accidental contact with the abrasive
wheels.
Mounting the Protective Guard
Loosen the screw
12
and place the protective
guard
13
on the spindle
collar
16
. Rotate it so
that the closed part of
the protective guard fac-
es you during the work-
ing operation. Fix the
protective guard in prop-
er position by securely
tightening the screw
12
.
Auxiliary Handle
Screw the auxiliary handle
3
onto the right or left side
of the head of the tool, depending on the kind of oper-
ation.
Hand Guard
For all work with the rub-
ber backing pad
5
, you
should mount the hand
guard
4
together with the
auxiliary handle
3
.
Exhaust Line
You can use an exhaust line to carry exhaust air away
from your workplace and, at the same time, achieve
optimal muffling. You also improve the operating con-
ditions, because your workplace will no longer be con-
taminated by oil-containing air and there are no longer
any raised dust or chips.
Unscrew the muffler at the air
outlet
2
and replace it with
the hose nipple
22
. Loosen
the hose clamp
20
of the ex-
haust hose
21
and attach the
exhaust hose over the hose
nipple
22
by firmly tightening
the hose clamp.
Connection to the Air Supply
The air tool is designed for an operating pressure of
6.3 bar (91 psi). For maximum performance, the inner
diameter of the hose is 10 mm with connection
threads of 1/4" NPT. To maintain full performance,
use only hoses with a maximum length of 4 m.
The supplied air must be free of foreign material and
moisture to protect the air tool from damage, contam-
ination, and rust.
The use of a compressed air maintenance unit is
necessary.
This ensures optimum functioning of compressed air
tools. Observe the operating instructions of the main-
tenance unit.
All fittings, connecting lines, and hoses must be di-
mensioned for the required air pressure and volume.
Avoid restrictions in the air supply resulting from, e.g.,
pinching, kinking, or stretching!
In case of doubt, measure the pressure with a pres-
sure gauge at the air inlet with the tool switched on.
