1. Replace fuel filter cartridge, v-belt, and intake air cleaner.
2. Check fuel lines for leakage.
3. Check battery cables and connectors.
4. Check engine monitoring and warning system.
Air Cleaners (Daily)
While the air filters should be checked daily and replaced when
necessary, there is no need to "over-service" the air filters. That
is, they require no cleaning and do not require the use of oil. If
the primary filter becomes clogged, simply replace it.
The saw utilizes both a primary air filter and a safety air filter,
(Figure 38). The air filter restriction light, (Item A, Figure 37) on
the engine status indicator (Item B, Figure 37), will illuminate
when the filter is plugged.
Avoid slips and falls!
Clean up all engine oil, hydraulic
oil, and diesel fuel spills
immediately.
