2.2.4 Chain container
• Extend the chain on the load side until the limit switch is triggered.
• Attach the free end of chain to housing (see chapter 2.2.2).
• Fit the chain container and allow the chain to run in: Plastic chain container (see figure 2-20) or textile chain container:
GPM 250: see figure 2-21, GP 250/500: see figure 2-22, GP 1000: see figure 2-23, GP 1600/2500: see figure 2-24.
Adjustment description (see figure 2-18):
• Provision only with model GPM 250: Loosen screws (1 + 2) and turn clamping strip (3) away (see figure 2-19).
• The geared limit switch must be deactivated mechanically by pressing the rocker switch (1) before drawing the chain in or when
changing the chain.
• Draw the chain in.
• Move to the highest hook position and turn the red switch wheel (2, rear) until it reaches the switch cam on the top limit switch (3)
(turn clockwise for the lowest hook position and anticlockwise for higher hook positions).
• Activate the rocker switch (1) (the rocker switch must latch into the switch wheel).
• Move to the lowest hook position, press the rocker switch (1) and turn the green switch wheel (4, front) until it reaches the switch cam
on the bottom limit switch (5) (turn clockwise for the lowest hook position and anticlockwise for higher hook positions).
• Activate the rocker switch (1) (the rocker switch must latch into the switch wheel).
Check the limit switch function: the limit stop and the bottom hook block may not touch the housing.

2.2.3 Limit switch
A geared limit switch is built in as standard in the electric chain hoists. This is also suitable as a regular limit stop with high switching
precision. The limit switch function (highest and lowest hook position) must be tested during start-up. Four different transmissions are
available depending on the lifting height:
