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 hous-
ing.

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.
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.
Bosch Power Tools
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 clock-
wise.
– 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 adjust-
er is under great tension, which can suddenly be released
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.
To increase the retraction force, press the spring catch
inward and turn the hex key 28 clockwise.
– For type 0 607 950 952, 4 turns (max.).
– For type 0 607 950 953, 5,6 turns (max.).
Type 0 607 950 954 | ... 955 | ... 956
 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 adjust-
er is under great tension, which can suddenly be released
when pushing in the hex key.
Insert hex key 9 into set screw 29. The set screw acts on the
spring catch of load-capacity adjuster 6.
To decrease the retraction force, turn hex key 9 counter-
clockwise.
To increase the retraction force, turn hex key 9 clockwise.
– For type 0 607 950 954, 11½ turns (max.).
– For type 0 607 950 955, 10 turns (max.).
– For type 0 607 950 956, 4¼ turns (max.).
