Maintenance

AIR FILTERS
Use only original equipment replacement parts. The use of alternate or
third party components can cause unsafe operating conditions, and will
void your warranty.
We suggest following a maintenance schedule as follows:
Flush every 200 hours of operation or as needed. Do not use water to
flush the tank. Use fresh 1-K kerosene only.
The Air Intake Filter should be replaced or washed with soap and water
and dried thoroughly every 500 hours of operation, or less, depending on
conditions.
The Output and Lint Filters should be replaced every 500 hours of opera-
tion or less, depending on conditions.
NOTE:
Use of diesel may require additional maintenance.
