MAINTENANCE PLAN 4.7.4 MAINTENANCE EVERY 10 HOURS OF OPERATION 4.7.4.a LUBRICATING THE JOINTS 180 IMPORTANT • Clean the grease nipples before applying the greasing pump. • After lubrication, remove all the contaminated grease that may have spread out of the nipples. • If the machine is used in difficult conditions, carry out these operations more frequently than usual. This maintenance operation must be carried out with the front bucket resting on the ground and the backhoe equipment completely extended and resting on the ground, too, as indicated in the figure. Use a syringe and the prescribed grease. (See “4.3 FUEL, COOLANT AND LUBRICANTS” and diagram 4.5.1).
IMPORTANT • As a general rule, it is important to consider that each cylinder is provided with two grease nipples po- sitioned on the couplings and that each pin serving as fulcrum point for a movement is provided with at least one grease nipple.
