Servicing the main valve, Fig. 26
To withstand and operate flawlessly, the detent end A, the spool shifter joint B and the
ball joint of the control valve require regular lubrication. Lubrication of the valve is par-
ticularly important if the machine is to be left standing for several months. If the parts of
the detent have become rusty, the machine will not operate flawlessly.
Lubricating the detent end of the valve, Fig. 26, point A
Removing the hexagon socket screw in the middle of the end plate of the detent end of
the valve, lubricant can be sprayed onto the moving parts of the valve detent.
Only use oil that does not congeal in frost.
The easiest way is to use a spray bottle with a nozzle and pipe.
1. Insert the spray pipe in the hole and press 2-3 times for about 1 second at a time.
2. The oil spreads smoothly on the moving parts of the detent end.
Lubricating the spool shifter, Fig. 26, point B
The spool shifter is equipped with a pin and a ball joint that require regular mainte-
nance and lubrication.
1. Lift up the edge of the protective rubber of the spool shifter.
2. Spray lubricant on both sides of the pin and on the ball joint.
3. At the same time, check that the rubber is intact.
