Maintenance
4. always be sure that the battery cables are properly
connected to the battery terminals as shown below.
Generally the red cable will be connected to the
positive terminal of the battery, and the BlacK cable
will be connected to the negative terminal of the battery.
See Figure 44.

5. Disconnect the negative terminal ( - ) of the battery
during storage. If unit will be stored where ambient
temperature will drop to -15° C or less, remove and
store battery in a warm, dry place.
Bearing luBricaTion
Strike tube and drive tube bearings (Figure 45) require
lubrication daily. Lubricate all bearing zerk grease fittings
with EP3 grease or equivalent.
Figure 45. Zerk Fittings
warning
If the battery cables are connected incorrectly, electrical
damage will occur causing damage to the roller's
electrical circuits. Pay close attention to the polarity of
the battery when connecting the battery.
NOTICE
Failure to lubricate bearing grease fittings daily will
cause rotation of drive and strike tubes to stiffen. To
prevent contamination of the bearing, always insert
cap onto zerk fitting.
hydraulic oil sysTem
The hydraulic system consists of a hydraulic pump directly
coupled to the engine.
Hydraulic oil is filtered by a screen filter located in the tank
filler neck, a 10 micron inlet filter that connects to the hydraulic
tank and pump, and a 10 micron outlet filter that connects
from the cooler to the hydraulic tank. See Figure 46.
Figure 46. Hydraulic Filter Locations
It is recommended that ISO 46 type hydraulic oil or equivalent
be used when adding or replacing the hydraulic oil.
do noT use mulTi-viscosiTy oil. Cleanliness is a
very important part of proper hydraulic system operation.
Hydraulic oil is not only used to transfer power; it also
lubricates and cools the system components. Keeping the
hydraulic system clean can help reduce costly repairs.
The hydraulic oil level sight glass is located on the side of the
hydraulic tank This level should be checked daily. Oil must
be below the top and above the bottom of the sight glass.
do noT overfill! Care should be taken to clean the filler
cap before adding oil to the system. If hydraulic oil has to be
added, the machine should be inspected for leaks.
