OPERATING INSTRUCTIONS 

 

    

WARNING 

 

 

Inspection of Mower

:  Do not use the 

mower if any parts are not maintained in good 
operating condition.  Examine all moving parts 
prior to each use.  Look for excessive wear, bald 
drive tires or worn out front tires (normally 
smooth), cracks in parts, loose or missing bolts, 
cotter, linchpin or “hair” pins or cable yoke pins 
and replace before operating the mower.  Make 
sure all safety equipment provided with the 
mower is in good operating order, including all 
warning decals and the operator-presence 
device which stops the engine and blades when 
the foot-operated Operator Presence Control 
(OPC) switch is released.  To test the OPC, 
follow the instructions given later in this manual.  
Inspect the two anti-tip rollers and their 
respective bolts at the rear of the mower for 
tightness and proper operation.  Ensure that all 
parts of the Quad-Lever™ control system are 
tight and secure.  This is to reduce the possibility 
that the mower could have a loss of control or 
safety. 
 

Basic Operation

:  The following procedures 

are to guide you through the basic operation of 
the mower.  You should be a qualified mower 
operator according to the safety section of this 
manual.  If this is your first time, operation 
should only be done with the assistance of your 
dealer on a level area.  You should go through 
each step, in the order indicated, every time you 
start the mower. 
 

Before starting the engine 

 

• Make sure the control levers are in the 

exact neutral position 

 

• Apply the parking brake if it is not already 

set. 

 

• Turn OFF the blade engaging switch if it is 

on. 

 

• Turn fuel valve to the “ON” position. 

Starting the engine 

Electric Start: 
•Start the engine according to the engine 

manufacturer’s recommendation, see engine 
manual.  Set the throttle control lever near 
mid throttle, pull out on the choke control 
knob and turn the key to the start position.  
Do not engage the starter for more than ten 
(10) seconds at a time.  This may overheat 
the starter and the wiring systems.  Wait ten 
(10) seconds between attempts.  If the 
engine does not start after several attempts 
or stalls frequently, take the mower in for 
service. 

After starting the engine according to the engine 
manufacturer’s recommendation, push in on the 
choke control knob to open the choke valve, let 
the engine run for several minutes to get the 
hydraulic fluid circulating through the pumps, 
etc. and to allow the engine to warm up.  Do not 
over-rev a cold engine. 
 

Unusual noises or irregular operation: 

As you drive the mower, listen for any unusual 
noises and test for irregular operation and adjust 
or service as necessary. 
 

While standing, both feet should be firmly placed 
on the foot platform.  Set the engine speed 
about a fourth of the way from idle.  Release the 
parking brake.  Now try moving the hand control 
levers, one at a time, very slightly, forward and 
backward.  Check to see if the wheels move 
forward and backward according to the position 
of the levers.  If not, check to see that the pump 
release valves are closed.  With both feet still 
firmly placed on the foot platform, increase the 
engine speed to about half of the way from idle
