7. Check the engine idle RPM every 200 hours
and adjust, if necessary. NEVER adjust engine
RPM without a tachometer. Refer to Nissan
Engine Operation and Service Manual.

container daily. If no coolant is seen, remove
the cap and add coolant. Change the coolant
with a 70:30 coolant to water ratio every 1000
hours.
9. Replace the in-line gas filter yearly.
NOTE: For additional engine service
information, obtain a “Nissan A-12 Service and
Repair Manual” from any authorized Nissan
Service Center. If service or repair is required,
contact an authorized Nissan Service Center.

VACUUM PUMP
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use AEON
PD Synthetic Blower Lubricant in the gear end of
the vacuum pump for all operating temperatures.
AEON PD is formulated especially for positive
displacement blower service to provide maximum
blower protection at any temperature. One filling of
AEON PD will last a minimum of 2 times longer than
a premium mineral oil.
NOTE: AEON PD (Part# 05-008039) is the oil
which PROCHEM puts in the vacuum pump at
the factory. Topping off or adding petroleum oil
to synthetic oil is NOT recommended.
If not using AEON PD synthetic blower lubricant,
use oils with rust and oxidation inhibitors, anti-
foam additives and the viscosity’s listed on the
chart on the next page.
1. Check the oil level weekly to assure the proper
level. PROPER LEVEL cannot be
overemphasized. Too little oil will ruin bearings
and gears. Too much oil will cause overheating.
Use Figure 19 as a guide when adding oil.
