5. After setting the air gap at .025 in., install the spark
plugs in the cylinder head. Tighten the plugs to
10–15 ft.-lb. (14–20 N⋅m). Push the wires onto the
spark plugs.
6. Lower the hood and secure the latches.
Cleaning the Cylinder Head
Fins
To avoid overheating and possible engine damage, clean
the cooling fins on the cylinder head every day if necessary.
1. Disengage the hood latches and open the hood.
2. Pull the wires off of the spark plugs.
3. Clean dirt, grass, and chaff from the outside of the
cylinder, the cylinder head fins, and the air intake
screen.
4. Push the wires onto the spark plugs.
5. Lower the hood and secure the latches.
Changing the Gear Case Oil
and Filter
Change the hydraulic oil and filter initially after 25 hours of
operation; thereafter change them every 200 hours of
operation.
Important The gear case oil and filter must be changed
immediately when any contamination, sludge, water or
condensation appears.
1. Disengage the hood latches and open the hood.
2. Place a drain pan under the bottom of the gear case.
Clean the area around the drain plug (Fig. 28).
Note: When draining the oil, use a funnel or some type of
channel to divert the draining oil away from the machine
components and into a drain pan.

3. Remove the drain plug and allow the oil to flow into a
drain pan. After the oil has drained, install the oil drain
plug.
4. Remove the oil filter (Fig. 29), mounted below control
panel base, and discard the filter. Thoroughly clean the
filter mounting surface and make sure that a new gasket
is installed in the new filter.

5. Fill the new filter with new Mobil DTE 26 hydraulic oil
or equivalent oil (refer to Fluid Recommendations,
page 10). Apply a thin film of clean oil to the filter
gasket.
6. Install the new filter by hand until the gasket just
touches the mounting surface, then turn it an additional
1/2 to 3/4 turn.
7. Remove the filler cap and add approximately 4–5 quarts
of Mobil DTE 26 hydraulic oil or equivalent oil (refer
to Fluid Recommendations, page 10) to the gear case
reservoir. Install the filler cap.
8. Check for leaks around the oil filter. Tighten the filter
only enough to eliminate leaks. Do not overtighten.
9. Lower the hood and secure the latches.
Changing the Pump Case Oil
Change the pump oil initially after 25 hours of operation;
thereafter change it every 200 hours of operation.
Important The pump case oil must be changed
immediately when any contamination, sludge, water or
condensation appears.
1. Disengage the hood latches and open the hood.
2. Place a drain pan under the pump case. Clean the area
around the drain plug on the bottom of the case
(Fig. 30).
Note: When draining the oil, use a funnel or some type of
channel to divert the draining oil away from the machine
components and into a drain pan.
