Lubricating the chain

 

A well-lubricated chain wears much slower and can be used considerably longer. The chain must be lubricated before operation.

 

*   Press the LIFT button and allow the chain to run into the chain box. Lubricate the chain during its movement.

Lubricant: “Chainlife S”. For details, see page 83.

*   Apply additional lubricant to the unstressed chain in the chain box so that it flows into the joints of the chain links.

 

 

Only for GM2, GM4 and GM6 (GM6 with plastic chain box)

The illustrations show a chain box being installed on the GM6 chain hoist. Installation on a GM2 or GM4 chain hoist is very similar.

 

Installing the chain box

Bolt

SL safety clip

 

Chain box

*   Place the chain in the chain box.

*   Turn the chain box as shown in the figure (slanted side facing outward).

*   Use the bolts to install the chain box on the chain hoist.

─     For GM2: Use a bolt to fix the chain box to the chain hoist.

─     For GM4 and chain box with one hole: Use a bolt to fix the chain box to the chain hoist.

─     For GM4 and chain box with two holes: Use a bolt to fix the chain box to the chain hoist. Use the inner holes of the chain box. The outer holes remain free.

─     For GM6 and plastic chain box: Use two bolts to fix the chain box to the chain hoist.

*  Secure the bolts with the SL safety clips (1x or 2x).

 

 

Only for GM8

 

Attach buffer

 

Suspension straps

Buffer

Bolt

*   Turn the buffer as shown in the figure (rounded side facing inward).

*   Push the buffer between the suspension straps on the chain hoist.

*   Push the short bolt through the outer holes of the suspension straps and the buffer.

 

 

Only for GM6 (GM6 with chain box with metal frame) and GM8

The illustrations show a chain box being installed on the GM8 chain hoist. Installation on a GM6 chain hoist is very similar.

 

Installing the chain box

Inner hole

Bolt

Chain box

SL safety clip

*   Place the chain in the chain box.

*   Turn the chain box as shown in the figure (bar facing outward).

*   Use the bolts to install the chain box on the chain hoist.

─     For GM6 and chain box with metal frame: Use a bolt to fix the chain box to the chain hoist. Use the inner holes of the suspension strap. The outer holes of the suspension strap remain free.

─     For GM8: Use a bolt to fix the chain box to the chain hoist. Use the inner holes of the suspension strap. The buffer is fixed to the outer holes of the suspension straps.

*  Secure the bolts with the SL safety clips (2x).

 

 

Only for GM8

 

Turn second fall straight

Chain anchor point

Second fall

*   Check the chain anchor point: The second fall should extend straight to the bottom block and not be twisted.

 

If necessary:

*  Turn the chain anchor point.

 

 

Only with an electronic hoist limit switch

 

Referencing the electronic hoist limit switch

*   The electronic hoist limit switch needs to be referenced again. See page 57.

*   Check the switching points (upper and lower) and correct if necessary.

─     The saved switching points are retained after referencing and therefore do not need to be reset.

─     If the switching points are moved equally, all the switching points can be corrected at the same time by changing the reference point accordingly.
