Hazards
There are several hazards you should be aware of as you service
the lift. Before working on the machine be sure to insert any and
all maintenance devices. See figure 1.
DANGER!
The machine may use a power supply of up to 575 Volts.
This voltage can kill you. Do not work with the electrical
parts unless you are a qualified electrician.
CATUION!
Do not change the setting on the relief valve in the pump.
If you do, this may damage the machine and you may be
hurt. The relief valve has been included for the protection
of all of the workers who use the machine.
CAUTION!
Before working on the machine, be sure to release pres-
sure on the hydraulic system.
CAUTION!
The warning labels on the machine are there for the
safety of the operator. If the labels are worn or missing,
replace them.
Routine periodic maintenance
Every month:
1. Visually inspect the center pivot bearing, cylinder clevis pins and
bushings. Apply oil or WD-40 to all parts listed above.
2. inspect hoses and fittings for leaks.
Note: Although the bearings are “lifetime lubricated” their perfor
-
mance may be extended by additional periodic lubrication (WD-40).
3. Check the level and appearance of the hydraulic fluid. Use a
dipstick to check the oil level and add oil if necessary. Change the
oil if it has darkened from its original color, turned milky white or if
it feels gritty or sticky.
4. Inspect the overall condition of the lift; looking for loose or worn
out components.
NOTICE
It is important to use hydraulic fluid with the correct grade
and properties. The hydraulic fluid the machine is provided
with is Conoco AW-32.
Every six months:
1. Visually inspect the center pivot bearing, cylinder clevis pins and
bushings. Apply light oil or WD-40 to all parts listed above.
WARNING!
If a hydraulic fitting becomes loose or if a hydraulic
hose breaks, the hydraulic fluid will escape from the
system under pressure. Someone may be hurt or the
product or the machine may be damaged.
2. Drain all of the hydraulic fluid from the tank and cylinders and
discard it.
3. Remove the spin on filter from the tank. Discard and install new
filter.
4. Refill the tank with new hydraulic fluid. The hydraulic fluid should
be approximately 3/4” from the top of the tank.
5. Inspect the overall condition of the rotator; looking for loose or
worn out components.
6. Add grease to all grease fittings.
