5.3 Lubrication
5.3.1 Boom Pivoting And Sliding Joints, Monthly
Lubricate all shafts and bearings with a liberal amount of multi-purpose grease. Bearings and shafts should be re-
greased monthly. All boom motions should be smooth and constant. Jerky operation may indicate mechanical
damage to the boom, to a cylinder, or the rotation motor.
5.3.2 Boom Rotation Drive Chain & Sprockets, Every 6 Months
Because of the operating environment, the boom rotation drive chain and sprockets rapidly accumulate dust and dirt.
At the recommended interval, thoroughly flush the chain with an approved solvent to rinse off all accumulated dirt.
Then, while the boom is rotating, brush on a coat of lubricant. Be sure to work the lubricant into the chain pin joints.
5.4 Hydraulic Power Unit Service
The hydraulic power unit requires scheduled maintenance for long life and trouble free operation. Recommended
hydraulic oil is "IS Blue All Season" (Viscosity 73.6 @ 100deg F). This is a high-performance anti-wear oil, with
excellent low-temperature performance, suitable for environments with wide fluctuations in ambient temperature. An
alternative is Exxon Mobil Univis N32 (Viscosity 177 @ 100deg F).
NOTE:
DO NOT MIX OIL TYPES. COMPLETELY DRAIN AND FLUSH THE SYSTEM COMPONENTS WHEN
CHANGING THE HYDRAULIC OIL.
5.4.1 Hydraulic Oil Inspection, Daily
A. Check the reservoir fluid level with the probe operating. The level must be above the RED Low Oil Level bar
on the sight gage. Replenish reservoir as necessary to maintain minimum level.
B. Check fluid temperature after the truck probe has operated for a time. Fluid temperature should stabilize
between 110 and 135 degrees Fahrenheit.
Probable causes of hydraulic fluid overheating include:
1. Prolonged periods of continuous operation in a hot environment. A heat exchanger may have to be
installed to cool the fluid. If the high temperature environment is a temporary condition, a forced draft of
cooling air may be sufficient.
2. Low hydraulic fluid level. Fluid circulates through the system so rapidly that it can't transfer heat to the
reservoir. Add fluid.
3. Dirty power unit. A coating of hydraulic fluid and dirt prevents the power unit from shedding heat to the
surrounding air. Clean the hydraulic power unit.
4. Pump cavitation is usually signaled by a crackling or popping sound originating in the pump, this is most
often caused by a clogged suction strainer resulting in the fluid vaporizing in the pump. Cavitation
causes the fluid to overheat and loss of system pressure. The pump and motor will run hotter, and the
pump will eventually be destroyed. Identify and correct the problem as soon as possible.
