MAINTENANCE
7-42
IMPORTANT:
y
When connecting hydraulic hoses and pipes, take
special care to keep seal surfaces free from dirt and
to avoid damaging them. Keep these precautions in
mind:
y
Wash hoses, pipes, and the tank interior with a
washing liquid and thoroughly wipe it out before
reconnecting them.
y
Only use O-rings that are free of damage or defects.
Be careful not to damage them during reassembly.
y
Do not allow high pressure hoses to twist when
connecting them. The life of twisted hoses will be
shortened considerably.
y
Carefully tighten low pressure hose clamps.
Do not overtighten them.
y
When adding hydraulic oil, always use compatible
oils; do not mix brands of oil. As the machine is
filled with Super EX 46HN when it is shipped from
the factory, use it as a general rule. When selecting
to use another brand of oil listed in the table
“Recommended Hydraulic Oil”, be sure to completely
replace the oil in the system.
y
Do not use hydraulic oils other than those listed in
the table “Recommended Hydraulic Oil”.
y
Never run the engine without oil in the hydraulic oil
tank.
