6.2

Before use

• Connect the hydraulic hose to the tool and to the pump. See section 5.3.2.
• Start the pump.
6.3 Tool movement
The spreading arms open and close relatively quickly until they encounter resistance. Then the pump
will build up the required pressure for spreading, cutting, pulling or squeezing.
WARNING
Take extreme care during tool movement. Because of the enormous power of the tool parts
of the body can easily be crushed or pinched.
6.4 Spreading
CAUTION
Make sure that the spreading tips have been properly attached to the spreading arms.
6.4.1 Initial opening is sufficient
• Close the spreading arms completely.
• Place both spreading tips between the parts to be spread.
• Force the parts apart by opening the spreading arms.
6.4.2 Initial opening is insufficient
• Open the spreading arms.
• Place one spreading tip in the opening.
• Close the spreading arms until the material is clamped.
• Bend the clamped material out of the way.

• Force the parts apart by opening the spreading arms.
6.4.3 No initial opening
• Use a different tool or accessory to make an opening.

6.5 Cutting
