®
Replace the in-line fuel filter yearly.
NOTE: Additional engine service information
can be obtained from the provided Operation and
Maintenance manual. If service or repair is
required, contact an authorized Kohler Service
Center. They will require the serial number of the
engine.
VACUUM PUMP
NOTE: Refer to the provided Vacuum Pump
Operation and Service Manual for specific
instructions.
Lubrication: SAPPHIRE SCIENTIFIC
requires that you use only AEON PD-XD
Synthetic vacuum pump Lubricant in both sides
of the vacuum pump for all operating
temperatures. AEON PD-XD is formulated
specifically for positive displacement vacuum
pump service to provide maximum vacuum pump
protection at any temperature.
NOTE: AEON PD-XD (Part # 13-004) is the
only oil that SAPPHIRE SCIENTIFIC puts in
the vacuum pump at the factory. Adding
petroleum oil to synthetic oil is NOT
recommended.
1. Check the oil level daily to ensure it is at the
proper level. Too little oil will damage and ruin
the bearings and gears. Too much oil will result
in overheating.
NOTE: Two drains are on your vacuum pump.
Ensure that BOTH sides of the vacuum pump are
filled to their proper level when servicing.
2. A lubrication port has been provided at the
front of the console, to prevent rust from building
up inside of the vacuum pump.
Run the unit for at least 2 minutes to remove any
moisture from the vacuum pump. Then, spray
WD-40 (or Equivalent) into the lubrication cup
for 5 seconds while the unit is running and the
vacuum inlet port is sealed. This procedure
should be done at the end of every working day.
3. Drain, flush and replace the oil every 1000
hours or 1 year, whichever comes first.
WATER PUMP
Refer to the provided Water Pump Operation
Manual for specific instructions.
1. Check the crankcase oil level daily to ensure
the proper level. If the level has dropped,
check for the source of leakage and repair.
2. After the first 50 hours of operation, change
the crankcase oil with general pump oil. Change
the crankcase oil every 500 hours thereafter.
