Checking The Torque Of The Wheel Nuts; Breaking In The Machine; Starting The Engine; Shutting Off The Engine - Toro Greensmaster TriFlex 3420 Operator's Manual

Checking the Torque of the
Wheel Nuts
WARNING
Failure to maintain proper torque of the wheel
nuts could result in personal injury.
Torque the wheel nuts to 95 to 122 N∙m (70-90
ft-lb) after 1-4 hours of operation and again
after 10 hours of operation. Torque every 200
hours thereafter.
To ensure even distribution, torque the brakes in a
star pattern.

Breaking in the Machine

Refer to the engine manual supplied with the
machine for oil change and maintenance procedures
recommended during the break-in period.
Only 8 hours of mowing operation is required for the
break-in period.
Since the first hours of operation are critical to future
dependability of the machine, monitor its functions and
performance closely so that minor difficulties, which
could lead to major problems, are noted and can be
corrected. Inspect the machine frequently during
break-in for signs of oil leakage, loose fasteners, or
any other malfunction.

Starting the Engine

Important:
Do not use ether or other types of
starting fluid.
Note:
You may need to bleed the fuel system before
starting the engine if any of the following situations
have occurred:
•
Initial start up of a new engine
•
The engine has ceased running due to lack of fuel.
•
Maintenance has been performed upon fuel
system components; ie. filter replaced, etc.
Refer to your engine owner's manual.

allow it to move to the O
7. Allow the engine to warm up for a few minutes
before operating.
Important:
When starting the engine for
the first time or after an overhaul of the
engine, operate the machine in forward and
reverse for one to two minutes. Turn the
steering wheel to the left and right to check
the steering response. Then shut the engine
off (see Stopping in Starting and Stopping
the Engine) and wait for all moving parts to
stop. Check for oil leaks, loose parts and
any other noticeable malfunctions.

Shutting Off the Engine
