SERVICE AND MAINTENANCE
Changing the Engine Oil
The oil in the engine should be changed every 25 hours of operation.
1.
To gain access to the oil drain valve on the engine, the right
handle brace tube should be pivoted forward.
a.
Remove the upper star knob and carriage screw on the right
side of the handle, Figure 11.
b.
Pivot the brace tube towards the front of the mower to allow
room to connect the oil drain hose to the oil drain valve.
Figure 11.

2. Pop off the protective cap on the end of the oil drain valve to
Figure 12
3.
Remove the oil fill cap/dipstick from the oil fill tube. Figure 12.
4.
Push the oil drain hose (packed with this manual) onto the oil
drain port. Route the opposite end of the hose into an appropriate
oil collection container with a capacity great enough to collect the
used oil.
5.
Release the valve by pressing the two tabs inward while pulling
the valve out. The oil will begin to drain out of the engine.
6.
After the oil has finished draining, press the two tabs inward and
push the oil drain valve back in to lock the valve closed. Remove
the hose, and re-cap the end of the oil drain valve to keep debris
from entering the drain port.
7.
Refill the engine with new motor oil until the oil level on the
dipstick reads FULL. Replace the oil fill cap/dipstick.
8.
Pivot the right handle brace tube back into position. Align the
middle hole in the brace tube with the hole in the handle. Secure
with the star knob and carriage screw removed earlier.
Only use high quality detergent oil rated with API service clas
sification SF or SG. Select the oil's SAE viscosity grade according
to your expected operating temperature. Figure 13. Although
multi-viscosity oils (5W30,10W30 etc.) improve starting in cold
weather, these multi-viscosity oils will result in increased oil con
sumption when used above 32°F. Check your engine oil level more
frequently to avoid possible engine damage from running low on oil.
