10.0 MAINTENANCE AND INSPECTION SCHEDULE
It is recommended that maintenance and inspection is done on a scheduled basis. Maintenance
requirements will naturally vary widely for each installation and specific operating conditions. It is
suggested that a complete inspection be performed with the necessary maintenance at the end of the
first day, the first week, the first month and the first 3 months. These inspections will be indicative of
how often future maintenance will be necessary.
EVERY WEEK
Inspect the Filter cartridge. Clean or replace as required. Remove any fines collected from the catch
pan. This time interval should be shortened if experience indicates unusual dust loading.
Check the system for air leaks and correct as required.
EVERY MONTH
I
nspect the vacuum breaker valve filter/silencer. Clean or replace as required.
EVERY 3 MONTHS
Units equipped with permanently lubricated motor bearings do not need lubrication. All motors should
be examined on an individual basis.
Units equipped with ball bearing motors are factory greased and should be re-lubricated with a high-
grade ball bearing grease rated for temperature and duty cycle required.
WHEN ADDING LUBRICANT
1.
Remove filter plugs at the bearings and install grease fittings suitable to your grease gun. Also,
remove the drain plugs at the bearings.
2.
Add ball bearing grease until all of the old grease is expelled through the drain hole.
3.
Run motor with drain plug removed to eliminate excess grease.
4.
Clean and replace drain plugs.
5.
Check motor (s) amperage (see Engineering Data Sheet).
EVERY 6 MONTHS
Check for loose electrical connections. Tighten all bolts and nuts. Check V belts. Adjust or replace as
required.
