Ariens HYDROSTATIC S-12 - Filling the Tank; Change Engine Oil

Before attempting to push the tractor be sure the hy-
drostatic control lever is in neutral (N) and the free
wheeling valves pushed in. If the lever is in the "Park-Start"
position the rear wheels will be mechanically locked.
The tractor will not move under power uniess the free
wheeling valves are closed (button out), by rotating cam.
/MPORTANT: DO NOT PUSH OR TOW TRACTOR
LONG DISTANCES AS INTERNAL TRANSMIS¬
SION DAMAGE COULD RESULT. LOAD TRAC¬
TOR ON A TRAILER OR TRUCK WHEN MOVING
LONG DISTANCES.

FILLING THE TANK
The fuel tank filler cap is located behind the seat, see
Figure 7. Wipe the dust and dirt from around the cap before
removing it to prevent dirt from falling into the tank while
filling. Use an approved gasoline container and keep it clean.
The fuel tank capacity is 4.5 U.S. gallons.
Use reguler grade gasoline. Be sure the gasoline is clean and
fresh. Do not use premium gasoline. Do not mix oil with
gasoline.
ENGINE
Check the engine crankcase oil level daily or every 5
hours operation. It is essentiel that the oil level be maintained
in the "safe" operating range as shown in Figure 8 at all
times or serious engine damage could result.
To check the oil, stop engine and wipe all dirt and dust
from around the dip stick, Figure 9. Pull dip stick out, wipe
off the oil, re-insert dip stick and push it down tight. Pull
the dip stick out and observe the oil level. Add sufficient oil
of the proper viscosity to bring the oil up to the "fill"
(F) mark, see Figure 8. Be sure tractor is level to correctiy
read dip stick.
NOT EXCEED
"F" MARK
FIGURE 8
DO NOT OVERFILL — Oil level must never exceed full mark.
Oil capacity of the engine crankcase is 4 U.S. pints.
Use Ariens Gard-N-Yard oil (SAE 10W-30 SE classification)
when using lawn and garden attachments. Use Ariens Sno-
Thro oil (SAE 5W-20 SE classification) when using snow
removal attachments.
CHANGE ENGINE OIL
When the tractor is new, the oil should be changed after
the first 5 hours of operation.
Under normal operating conditions, the oil should be
changed every 25 hours of operation. If extremely dusty or
dirty conditions prevail, change oil more frequently. See
Engine Owner's Manual.
Drain the crankcase by removing the drain plug, shown in
Figure 10, and allow the oil to drain into a container. If
possible, run engine just prior to changing oil, as the oil will
flow more freely and carry away more contamination when
hot.
