Assembly
The device onto which the suspension quick-link 2 and
the securing eye 4 of the balancer or spring pull are to
be attached must be dimensioned with with a safety
factor of 5. For safe operation with the balancer or spring
pull, calculate the weight of the balancer or spring pull (see
"Technical Data") plus the maximal load capacity (weight
of the attached tool) and multiply the sum by 5.
Immediately replace balancers and spring pulls that
have fallen down or crashed! Have damaged balancers
and spring pulls repaired through an authorized customer
service agent for Bosch power tools.
Mounting a Balancer
Type 0 607 950 938 | ... 939
Mount the balancer via suspension quick-link 2 to a stationary
mounting location with sufficient stability.
Tighten lock nut 3 on suspension quick-link 2 so that the bal-
ancer can not slip or jump out of the suspension quick-link.
Fasten securing eye 4 independent from suspension quick-
link 2.
Pay attention that the movability of the balancer is not im-
paired by the safety chain 1. A back and forth motion in the di-
rection of the balancer must be possible.
The possible falling distance in case of falling down must not
exceed 1 m.
Mounting a Spring Pull
Type 0 607 950 950 | ... 951
Mount the spring pull via suspension quick-link 2 to a station-
ary mounting location with sufficient stability.
Type 0 607 950 952 | ... 953 | ... 954 | ... 955 | ... 956 |
... 957 | ... 958
Mount the spring pull via suspension quick-link 2 to a station-
ary mounting location with sufficient stability.
Tighten lock nut 3 on suspension quick-link 2 so that the
spring pull can not slip or jump out of the suspension quick-
link.
Fasten securing eye 4 independent from suspension quick-
link 2.
Pay attention that the movability of the spring pull is not im-
paired by the safety chain 1. A back and forth motion in the di-
rection of the spring pull must be possible.
The possible falling distance in case of falling down must not
exceed 1 m.
Connection to the Air Supply
Type 0 607 950 938 | ... 939
Pay attention that the air pressure is not below 6.3 bar
(91 psi), as the air tool is designed for this operating
pressure.
For maximum performance, the inner hose diameter sizes as
well as the connection threads must correspond with the val-
ues listed in the table "Technical Data". To maintain full per-
formance, use only hoses with a maximum length of 4 meters.
1 609 929 X58 | (12.5.11)
The supplied air must be free of foreign material and moisture
to protect the air tool from damage, contamination, and rust.
Note: The use of a compressed air maintenance unit is neces-
sary. This ensures optimum functioning of compressed air
tools.
Observe the operating instructions of the maintenance unit.
All fittings, connecting lines, and hoses must be dimensioned
for the required air pressure and volume.
Avoid restrictions in the air supply resulting from, e.g., pinch-
ing, kinking, or stretching!
In case of doubt, measure the pressure with a pressure gauge
at the air inlet with the air tool switched on.
Connecting the Air Supply to the Balancer (see figure A)
Screw hose fitting 14 into the connection socket at air inlet 7.
To avoid damage to interior valve components of the balancer
when screwing hose fitting 14 in or out, it is recommended to
counter-hold the projecting connection socket of air intake 7
with an open-end wrench (size 17 mm).
Loosen the hose clamps 15 of supply-air hose 16. Slide one
end of the supply-air over hose fitting 14 and retighten the
hose clamp. Work the other end of the supply-air hose over
coupling nipple 17 and fasten the supply-air hose by retight-
ening the other hose clamp.
Screw a quick hose connector 18 in the air outlet of the main-
tenance unit 19. Quick hose connectors make possible a
quick connection and, when uncoupled, thea shut off the air
supply automatically.
Insert coupling nipple 17 into hose connector (coupling) 18
to connect the supply-air hose to the filter/regulator-lubrica-
tor.
Connecting the Air Tool to the Balancer (see figure B)
Connect or remove the air tool to the quick hose con-
nector 12 only when the compressed-air hose is drawn
in completely. Pulled out compressed-air hoses not under
load can whip back and cause injuries.
Do not exceed the specified minimal and maximal load
capacity (see "Technical Data"). Exceeding the load
capacity range will cause damage to the spring in the
housing.
There are two possibilities for connecting the air tool to the
balancer:
– Purchase a threaded coupling nipple 20 that fits the air
inlet connector 21 of your air tool (see "Connecting to the
Air Supply" in the operating instructions of the air tool), so
that the air tool can be directly connected or removed at
the balancer.
Pay attention not to accidentally start the operation of the
air tool when connecting coupling nipple 20 with the quick
hose connector 12.
– Connect the hose nipple with barbed fitting 13 and the
hose fitting 22 from the delivery scope of your air tool with
a short piece of hose 23. Firmly tighten the hose clamps.
Pay attention not to accidentally start the operation of the
air tool when connecting hose nipple 13 with the quick
hose connector 12.
