During Use - Holmatro RA 5311 CL Manual De Instrucciones

6.3

During use

6.3.1 General
The plungers open and close quickly until they encounter resistance. Now the pump will build up the
required pressure and continue with spreading, pulling or crushing.
DANGER
Danger of crushing or pinching parts of the body. Note that hydraulic tools have an enormous
power, use only genuine Holmatro accessories and no other fasteners or chains
6.3.2 Spreading
WARNING
Do not let sharp objects touch the plungers.
Do not use too much force. If too much force is used the plunger can extend through the
opening and be damaged.
CAUTION
Never use more than one extension pipe at the same time.
Do not use an extension pipe without accessory, for example a grip head.
Avoid a crooked load with its risk of sliding off.
Watch out for the danger of being trapped when the plungers are retracted between cylinder
and accessory.
• Make sure that a grip head or other accessory is attached correctly at the end of the plunger(s) and
fixed side.
• Place the ram between the parts that must be spread.
• Extend the tool to force the parts apart.
6.3.3 Pulling
WARNING
The pulling accessories are intended solely for the horizontal movement of loads.
Hoisting is not permitted with these accessories.
WARNING
Make sure that the load is always supported from underneath. Continuously check the
behaviour of the load. Make sure that the tool can move freely during pulling and always
remains in a straight line between both pulling shoes.
• Open the plunger(s) fully.
• Place the pulling shoes correctly, the shortening hooks point with their openings upward.
• Attach the chains to the objects so that they cannot slip off.
• Pull the chains tight and hook them to the pulling shoes.
• Retract the plunger(s) fully.
6.3.4 Change tools
To change a tool during use:
• Disconnect the hoses from the tool in use. Refer to chapter 5.4.
• Connect the hoses to the other tool. Refer to chapter 5.3.
