your specifi c pump.
★
IMPORTANT: Follow the maintenance
procedures outlined in your OEM pump manual in
order to keep your warranty valid and to receive
maximum service life from your pump.
Basic Vacuum Pump Maintenance
Basic maintenance on your vacuum pump involves
maintaining proper oil fl ow, keeping the pump fi lled
with oil, and greasing the bearings.
•
Using the oiler sight window, check for proper oil fl ow
every time you operate your pump (Figure .4, page 15).
Refer to your OEM pump manual to determine specifi c
oiling rate (drip rate) for your pump.
If your vacuum pump is equipped with a manual
adjust drip oiler, pay close attention to the drip
rate and regulate it as necessary. Manual drip oilers
require periodic checking and adjustment. See
your OEM pump manual for specifi c instructions on
adjusting the drip oiler.
If your vacuum pump has an auto-lube oiler, the
oiler pump is preset at the factory and requires little
periodic adjustment. These oilers are adjustable,
however, should they go out of tune due to normal
operating conditions. See your OEM pump manual for
specifi c instructions on adjusting auto-lube oilers.
★
IMPORTANT: When adjusting your vacuum
pump oiler, use small adjustment increments (no
more than one turn at a time). This helps protect
against running the pump dry due to turning
the adjustment knob too lean or in the wrong
direction.
•
Check and refi ll the vacuum pump oil reservoir
every 4 hours of operation or daily.
It is essential to check the oil level regularly because
the pump consumes oil in the process of lubrication.
See your OEM manual for estimated average oil
usage for your specifi c pump.
Use only OEM recommended types and brands of
oil for your pump. Table .2 lists the manufacturer
recommended lubricants for the most popular
vacuum pumps supplied by Imperial Industries.
If you have difficulty obtaining a manufacturer
recommended oil, contact Imperial Industries about
its availability.
Some pump manufacturers recommend changing
the oil weight for summer and winter operation.
If you have a manual drip oiler on your pump, it is
necessary to adjust the drip rate when changing to
different weight oil. Reference your OEM vacuum
pump manual for instructions on adjusting the drip
oiler before you change the weight of oil in your
Hydraulic Components
If your Imperial Vacuum Tanker has hydraulic
components or drives, the hydraulic system requires
periodic checking and maintenance.
Check the oil in the hydraulic reservoir daily. Keep the
reservoir fi lled with AW-2 or equivalent hydraulic oil.
If the oil level drops, fi ll the reservoir, and then inspect
the complete hydraulic system for leakage. Before
making any repairs, be sure to relieve all pressure
in the system.
Most hydraulic systems will have a fi lter included in
the system. Change the fi lter every six months.
WARNING: Escaping hydraulic oil under
pressure can have suffi cient force to penetrate
your skin, which can cause serious injury. Before
operating hydraulic components, be sure all
connections are tight and hoses are not damaged.
Relieve all pressure before disconnecting
hydraulic lines or repairing leaks.
Hoist Vacuum Tankers
Hoist vacuum tankers have a hoist cylinder that raises
the front of the tank to allow solids to slide out the
rear dump hatch.
Grease the hoist system weekly at the lubrication
points described in table 4..
