Remove the grey plastic covers from the top of the mast. The covers are a push on fit. Remove the covers by gently levering
a thin blade or screwdriver between the mast and the covers.
2
Check the two M12 hexagon headed bolts that hold the boom pivot casting, are
fully tightened to 15 Nm
.
3
Replace the grey plastic covers to the mast.
4
Check the socket headed counter sunk screws (4), which hold the push handle to the mast. With a 4 mm A/F Allen key
confirm the screws are fully tightened to
5 Nm
.
5
Examine the actuator mounting point for damage or wear.
6
Without taking the mounting apart check for signs of wear on the set pin.

Check for excessive vertical and horizontal movement in the mounting. This will give a good indication of wear but if there is
any doubt the assembly should be stripped down as follows:
