Operating Instructions
Adjusting the Hose Retraction
Do not exceed the specified maximal hose-extension
length (see "Technical Data").
Type 0 607 950 938 | ... 939
Firstly, adjust the load capacity (see "Load-capacity Adjust-
ment for Balancers", page 15).
Loosen the Phillips screw of the hose-intake limiter 11.
Adjust the compressed-air hose 10 to the desired length and
retighten the Phillips screw of the hose-intake limiter.
Adjusting the Cable Length
Type 0 607 950 954 | ... 955 | ... 956 | ... 957 | ... 958
The spring pulls are provided ex-factory with a longer rope
25, so that the rope length can be individually adapted.
Guide the rope 25 through the rope grip 31.
Observe a minimum clearance of 1 m:
– For type 0 607 950 954|... 955|... 956, between the
rope-intake limiter 26 and the rope grip 31.
– For type 0 607 950 957|... 958, between the rope clamp
32 and the rope grip 31.
Adjust the desired rope length and press the rope clamp 30
together.
Cut off the excess rope behind rope clamp 30.
Adjusting the Rope Retraction
Do not exceed the specified maximal rope-extension
length (see "Technical Data").
Type 0 607 950 950 | ... 951 | ... 952 | ... 953 | ... 954 |
... 955 | ... 956
For these spring pulls, limiting the rope retraction is not pos-
sible.
Type 0 607 950 957 | ... 958
Firstly, adjust the load capacity (see "Load-capacity Adjust-
ment for Spring Pulls", page 15).
Loosen the screws of the rope fastener 32.
Adjust the rope 25 to the desired length and retighten the
screws of the rope fastener 32.
The elastic rope-intake limiter 26 can be moved manually.
Load-capacity Adjustment for Balancers
Do not exceed the specified minimal and maximal load
capacity (see "Technical Data"). Exceeding the load ca-
pacity range will cause damage to the spring in the housing.
Initial Installation
To extend the service life of the balancers, they are factory-
set to the lowest load capacity.
Attaching a load could completely unreel the hose, and could
thus cause damage or lead to injury.
Therefore, after suspending the balancer, set it to the maxi-
mal retraction force in unloaded condition (see "Adjusting the
Retraction Force").
Afterwards, the retraction force can be adapted to the sus-
pended load capacity.
Bosch Power Tools
Adjusting the Retraction Force
Connect the air tool to the balancer (see "Connecting the Air
Tool to the Balancer", page 14).
To decrease the retraction force, insert the hex key 9 into
the load-capacity adjuster 6, press the set screw for load-ca-
pacity adjustment inward and turn the hex key counterclock-
wise until the suspended load is balanced.
To increase the retraction force, insert the hex key 9 into the
load-capacity adjuster 6, press the set screw for load-capaci-
ty adjustment inward and turn the hex key clockwise until the
suspended load is balanced.
– For type 0 607 950 938, 4 turns (max.).
– For type 0 607 950 939, 2½ turns (max.).
The optimal retraction force is reached when the air tool can
be easily pulled to the desired position, and returns to the
starting position after releasing it.
Load-capacity Adjustment for Spring Pulls
Attach or remove loads only when the balancer rope is
drawn in completely. Pulled out ropes 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 ca-
pacity range will cause damage to the spring in the housing.
The spring pulls are factory-set to the maximal allowable load
capacity.
Fasten the load:
– For types 0 607 950 950, ... 951, ... 952 and ... 953, by
hooking on to the safety snap hook 27.
– For types 0 607 950 954, ... 955, ... 956, ... 957 and
... 958, by hooking on to the load hook 27 and tightening
the lock nut.
The correct load-capacity adjustment is reached when the
suspended tool can be easily pulled to the desired position,
and returns to the starting position after releasing it.
Type 0 607 950 950 | ... 951
To decrease the retraction force, press handwheel 24
against the housing and turn the pressed handwheel counter-
clockwise.
Turn the pressed handwheel in 60°-steps before allowing it to
engage.
To increase the retraction force, press handwheel 24 against
the housing and turn the pressed handwheel clockwise.
– For type 0 607 950 950, 2 turns (max.).
– For type 0 607 950 951, 4 turns (max.).
Type 0 607 950 952 | ... 953
Wear protective gloves and firmly hold the hex key
when adjusting the load capacity. When the maximal
load capacity is set, the spring of the load-capacity ad-
juster is under great tension, which can suddenly be re-
leased when pushing in the hex key.
Insert hex key 28 into the spring catch of the load-capacity
adjuster 6.
To decrease the retraction force, press the spring catch
inward and turn the hex key 28 counterclockwise.
