two flag terminals that are in the longer lead to 
the OPC switch in any order. 

2.  Continue routing this lead down the right side of 

the handle and connect the connector on the end 
to the park brake switch. 

3.  Fasten the harness to the left hand side of the 

handle using two large ties from the bolt bag.  
Fasten the harness to the right hand side of the 
handle using two small ties from the bolt bag.  On 
ECS models fasten the harness to the two small 
holes in the channel under the console using two 

small ties from the bolt bag. 

For electric start models: 

1.  Route the long unattached portion of the wiring 

harness up the left handle and under the console.  
Connect the two flag terminals to the OPC switch 
in any order.  Connect the connector to the key 
switch. 

2.  Fasten the harness to the left hand side of the 

handle using two large ties from the bolt bag.  On 
ECS models fasten the leads connecting to the 
OPC switch to the small hole in the channel 
under the console using a small tie from the bolt 
bag. 

Positioning the Discharge Chute

 

1.  Loosen the two (2) 5/16 nyloc nuts attaching 

discharge chute.  Lower the discharge chute into 
position.  Retighten nyloc nuts until chute is snug 
but can pivot freely. 

Servicing the Engine

 

Refer to Engine Owner’s Manual. 

Servicing the Hydraulic Oil

 

The machine is shipped with hydraulic oil in the 
reservoir.   

1.  Run the machine for approximately 15 minutes to 

allow any extra air to purge out of the hydraulic 
system.   

2.  Check hydraulic reservoir and if necessary fill 

the reservoir to the appropriate level with Mobil 1 
15W-50 synthetic motor oil.   

3.  Replace hydraulic reservoir cap and tighten until 

snug.  

Do not overtighten. 

 

NOTE

:  The baffle is labeled “HOT” and “COLD”.  

The oil level varies with the temperature of the 
oil.  The “HOT” level shows the level of oil when 
it is at 225°F (107°C).  The “COLD” level shows 
the level of the oil when it is at 75°F (24°C).  Fill 
to the appropriate level depending upon the 
temperature of the oil.  For example:  If the oil is 
about 150°F (65°C), fill to halfway between the 
“HOT” and “COLD” levels.  If the oil is at room 
temperature (about 75°F (24°C)), fill only to the 
“COLD” level. 

Grease Unit 

NOTE: Unit is not greased at the factory. 

1.  Lubricate fittings with NGLI grade #2 multi-

purpose gun grease. 

Refer to the following chart for fitting locations 
and initial pumps.
