• GREASING THE QUICK UNCOUPLING PLUNGER OF THE ATTACHMENTS
Periodically grease the quick uncoupling plunger of the attachments to ease
sliding and prevents rust from forming inside the cylinder chamber.
To perform this operation correctly, please follow the instructions below:
-
lower the telescopic boom
- stop the machine
- apply 30 ml of specific grease (see paragraph "FUELS AND LUBRICANTS")
with lubricator "B"
- start the engine, and perform a few plunger lifting cycles (plunger "A"). During
the first cycle, plunger "A" may move slowly, since the grease applied needs
to flow from the plunger to the spring. This delay is more significant at low
temperatures.
Excess grease inside the chamber is expelled from the side of plunger "A" during the first cycle.
EVERY 500 HOURS OR EVERY 6 MONTHS
