Never operate balancers and spring pulls provided with
a securing hook 4 and a securing chain 1 without them.
Electrically insulate balancers and spring pulls when
attaching welding tongs to them.
Install the balancer or spring pull in such a manner that
operating personnel does not work below suspended
loads. When pulling the tool on the balancer or spring
pull toward your workpiece, the angle should not exceed
10° (max.). Tools pulled at a larger angle can bounce back
and forth after releasing them, and injure persons.
Never exceed the load capacity range given on the type
plate 8. Danger of injury from falling down loads.
Never disassemble the balancer or spring pull. Opening
the housing can destroy the spring inside and make the
balancer or spring pull unusable.
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.
Safety Warnings for Balancers
Use safety equipment. Always wear eye
protection. Safety equipment such as a dust
mask, non-skid safety shoes, a hard hat, or
hearing protection used for appropriate condi-
tions will reduce personal injuries.
Use compressed air of Quality Class 5 in accordance with
ISO 8573-1 and a separate maintenance unit close to the
balancer. The compressed air supplied should be free of
foreign material and moisture in order to protect the balanc-
er against damage, contamination and the formation of rust.
Check the connections and the air supply lines. All
maintenance units, couplers, and hoses should conform to
the product specifications in terms of pressure and air vol-
ume. Too low pressure impairs the function of the bal-
ancer; too high pressure can result in material damage and
personal injury.
Protect the hoses from kinks, restrictions, solvents,
and sharp edges. Keep the hoses away from heat, oil,
and rotating parts. Immediately replace a damaged
hose. A defective air supply line may result in a wild com-
pressed-air hose and can cause personal injury. Raised
dust or chips may cause serious eye injury.
Make sure that hose clamps are always tightened
firmly. Loose or damaged hose clamps may result in un-
controlled air escape.
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.
Disconnect the air supply before carrying out mainte-
nance, making any load-capacity adjustments, or con-
necting or removing the air tool. This safety measure
prevents accidental starting of the air tool.
Check the suspension quick-link and the securing hook
daily for corrosion and damage. Have the balancer, es-
pecially the compressed-air hose, checked at least
1 609 929 X58 | (12.5.11)
once every year through an expert according to the re-
spectively appropriate country-specific regulations. In
case of damage, the balancer may not continue to be used.
Safety Warnings for Spring Pulls
Do not use the spring pull as a crane. Using spring pulls as
a crane can lead to personal injury and property damage.
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.
Put the spring pull out of operation when the pulled out
rope has sprung in without load. The sprung back rope
may possibly no longer be properly anchored or the rope
suspension may be broken.
Check the rope, the suspension quick-link and the
securing hook (where available) daily for corrosion and
damage. Have the spring pull, especially the rope,
checked at least once every year through an expert
according to ISO 4309. In case of damage, the spring pull
may not continue to be used.
