Safety Interlock System Tests; Operation - Briggs & Stratton 2691351-00 Operator's Manual

Note that the operator must be seated firmly in the rider
seat for the PTO to function.
Hour Meter (optional)
The hour meter (F, Figure 2) measures the number of
hours the key has been in the RUN position.
NOTE: The hour meter will register the passage of time
when the engine is running. The hour meter has a self-
contained power source so the total hours are always vis-
ible.
Transmission Release Levers
The transmission release levers (G, Figure 2) deactivate
the transmissions so that the unit can be pushed by hand
(see Pushing the Unit by Hand).
Fuel Tank Cap
To remove the fuel tank cap (H, Figure 2), turn counter-
clockwise.
Seat Adjustment
The seat (I, Figure 2) can be adjusted forward and back-
ward (see Seat Adjustment).
Ground Speed Levers
The ground speed levers (J, Figure 2) control the ground
speed and direction of the rider. The left lever controls the
left rear drive wheel and the right lever controls the right
rear drive wheel.
Moving a lever forward increases the FORWARD speed of
the associated wheel, and pulling back on a lever increas-
es the REVERSE speed.
The further a lever is moved away from the neutral position
the faster the drive wheel will turn.
See the Operation section for steering instructions.

Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for
the outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard start-
ing.
** Above 80°F (27°C) the use of 10W-30 may cause increased
oil consumption. Check oil level more frequently.
