removing it. If it is dirty or damaged, replace it.
Important: Never attempt to clean the safety
filter.
3. Inspect the new filter(s) for damage by looking into
the filter while shining a bright light on the outside
of the filter. Holes in the filter will appear as bright
spots. Inspect the element for tears, an oily film, or
damage to the rubber seal. If the filter is damaged
do not use it.
4. If you are replacing the safety filter, carefully slide
the new filter into the filter body (Figure 33).
Important: To prevent engine damage, always
operate the engine with both air filters and cover
installed.
5. Carefully slide the primary filter over the safety filter
(Figure 33). Ensure that it is fully seated by pushing
on the outer rim of the filter while installing it.
Important: Do not press on the soft inside area
of the filter.
6. Install the air cleaner cover with the dust cap oriented
as shown in Figure 33 and secure the latches.
Servicing the Engine Oil
Service Interval: After the first 8 hours—Change the
engine oil.
Before each use or daily—Check the
engine oil level.
Every 100 hours—Change the engine
oil.
Every 200 hours—Change the oil
filter.
Note: Change the oil more frequently when the
operating conditions are extremely dusty or sandy.
Oil Type: Detergent oil (API service SF, SG, SH, or SJ)
Crankcase Capacity: 58 ounces (1.7 liter) with the filter
removed; 51 ounces (1.5 liter) without the filter removed
Viscosity: Refer to the table (Figure 34).
Checking the Engine Oil Level
1. Park the machine on a level surface.
2. Lower the boom and set the parking brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Clean around the oil dipstick (Figure 35) so that dirt
cannot fall into the filler hole and damage the engine.

5. Unscrew the oil dipstick and wipe the end clean
(Figure 35).
6. Slide the oil dipstick fully into the filler tube, but do
not thread onto tube (Figure 35).
7. Pull the dipstick out and look at the end. If the oil
level is low, slowly pour only enough oil into the filler
tube to raise the level to the Full mark.
Important: Do not overfill the crankcase with
oil and run the engine; engine damage can
result.
