MAINTENANCE
Engine Maintenance
Refer to Briggs and Stratton OPERATION
AND MAINTENANCE INSTRUCTIONS.
Pump Maintenance
The pump requires no maintenance other than
draining the volute body after each use. If the
pump has been handling chemicals, salt water
or dirty water, flush entire system with clean,
fresh water for several minutes to remove all
traces of impurities.
Gear Case Maintenance
Drain and refill with one pint SAE 90 weight
gear oil after 100 hours of operation or one
year.
Spark Arresting Muffler
Every 50 hours, examine screen on muffler
and clean or replace. Inspect the gaskets on ei-
ther side of the sparker arrestor screen. If they
are cracked, broken or do not fit on the screen,
replace them. When replacing gaskets (115)
and/or spark arrestor (114), place a bead of sea-
lant such as Liquid Steel
on the side of the
spark arrestor opposite the bulge. This will in-
sure a seal in this area. Failure to do this may
cause priming difficulty. (Liquid Steel

registered trademark of the Loctite Corpora-
tion.)
