4.9.4 MAINTENANCE EVERY 100 HOURS OF OPERATION
4.9.4.a LUBRICATION
q
Clean the grease nipples before applying the greasing pump.
q
After lubrication, remove all the contaminated grease that may have spread out of the nipples.
q
If the machine is used in difficult conditions, carry out this operation more frequently than usual.
q
As a general rule, it is important to consider that each cylinder is provided with two grease nipples posi-
tioned on the couplings and that each pin serving as fulcrum point for a movement is provided with at
least one grease nipple.
q
When running in a new machine, lubricate every 10 hours for the first 100 hours of operation.
LUBRICATING THE COMPONENTS OF THE SWING SYSTEM
q
When injecting grease to lubricate the swing pinion and the ball-bearing ring, swing the turret slowly and grease
every 90°
1. Carefully clean the grease nipples (1) and (2), and inject the
grease indicated in the lubricant chart using a grease pump
(see "4.4 FUEL, COOLANT AND LUBRICANTS").
2. After the operation, remove any trace of grease.
(1) Swing pinion (1 point)
(2) Ball-bearing ring (1 point)
LUBRICATING THE WORK EQUIPMENT
q
After carrying out digging operations with the equipment immersed in water, always lubricate the pins
that have been in contact with water..
1. Position the machine as shown in the figure, lower the work
equipment to the ground and stop the engine.
