Operating Instructions
Adjusting the Hose Retraction
f
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
f
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
f
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.
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
f
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.
f
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
f
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.
