Initial Run-In Procedures; Starting The Engine; Ground Travel And Steering - Scag Power Equipment STT Operator's Manual

4.3 INITIAL RUN-IN PROCEDURES (First
Day of Use or Approximately 10 Hours)
1. Check all belts for proper alignment and wear at 2, 4
and 8 hours.
2. Change the engine oil and oil filter after the first 5
hours of operation. (See Section 7.4.)
3. Check oil level in the hydraulic system reservoir.
(See Section 7.3.)
4. Check for loose hardware. Tighten as needed.
5. Check interlock system for proper operation. (See
Section 4.2.)
6. Check tire pressure. Adjust pressure if necessary.
(See Section 7.10.)

4.4 STARTING THE ENGINE

CAUTION:
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a "runaway" engine condition
that could result in engine damage and/or personal
injury.
1. Be sure the fuel shutoff valve, located behind the
operator's seat, is completely open. (See section 7.5.)
2. Sit in the operator's seat and place the steering
control levers in the neutral position.
3. Engage the parking brake.
4. If the engine is cold, choke the engine as needed.
5. Move the engine throttle control to about half
engine speed.
6. Turn the ignition key to the START position and
release the key as soon as the engine starts. Do not
hold the key in the START position for more than 15
seconds at a time. Allow at least 60 seconds
between each cranking attempt to prevent
overheating of the starter motor. Prolonged cranking
can damage the starter motor and shorten battery
life.
7. Allow engine to warm before operating the mower.

4.5 GROUND TRAVEL AND STEERING

-IMPORTANT-
If you are not familiar with the operation of a
machine with lever steering and/or hydrostatic
transmissions, the steering and ground speed
operations should be learned and practiced in
an open area, away from buildings, fences, or
obstructions. Practice until you are comfortable
with the handling of the machine before
attempting to mow. Learn the operation on flat
ground before operating on slopes.
-IMPORTANT-
Start practicing with a slow engine speed and
slow forward travel.
Learn to feather the steering controls to obtain a
smooth operating action.
Practice operating the mower until you are
comfortable with the controls before proceeding
to mow.
Forward Travel
To travel forward with the mower, disengage the parking
brake and slowly push the steering control levers
forward an equal distance. The further the steering
control levers are pushed forward the greater the forward
speed will be. To increase the speed, push the steering
control levers further forward and to decrease the speed,
pull the steering control levers back.
To stop the forward travel, pull the steering control levers
back to the neutral position.
To steer the mower left while traveling forward, pull the
left steering lever back. The further the lever is pulled
back, the quicker the mower will turn left.
To steer the mower right while traveling forward, pull
the right steering control lever back. The further the
lever is pulled back, the quicker the mower will turn right.
