Check reservoir level using sight glass on the left side of the tank. If required, add to
reservoir with tractor transmission hydraulic oil (Shell DONAX TD FLUID or comparable).
Recheck oil level after the rotary hoe has been run and poil has been circulated through the
wheel and tyne motors. Routinely check level thereafter. DO NOT OVERFILL THE TANK.
Change the hydraulic oil filter after the first 50 hours of use. Change it after every 200
hours thereafter.
Add 1 quart of hydraulic oil to the reservoir with each oil filter change.
Check the tyne bolts after each use and tighten as needed., Check all hydraulic fittings for
leaks and tighten if necessary.
Tynes should be changed as often as needed for the machine to do satisfactory and
efficient rotary hoeing job. Use loctite stud and bearing adhesive/sealant on tyne bolt threads
to prevent loosening.
The grease zerks on both ends of the tynes shaft flange bearing should be greased after
every 4 to 8 hours of use.
Grease zerks on the wheel hubs should be greased once a week or so, depending upon
freewheel use.
IMPORTANT: The engine is normally serviced prior to shipping. However, shipping regulations
may prohibit this. Check levels and add oil and fuel as required before starting.
Service according to the engine manual before starting.
WARNING: Running the rotary hoe without hydraulic oil will cause serious damage to the
hydraulic pump. CHECK RESERVOIR LEVEL BEFORE STARTING THE MACHINE.

HOUR METER
The
SenDEC® TACH/HOUR
hour meter tracks the hours of machine operation in order for
routine maintenance to be performed on a timely basis.
Your
SenDEC
® hour meter is pre-set at the
SenDEC
® factory to go into
Flash Alert
mode at 25-
hour intervals. Although the engine manufacturer does not require changing engine oil this often,
due to heavy-duty use and extreme conditions inherent to tiller use, Red Roo
recommends frequent oil changes
strongly
.
Refer to this manual for equipment service requirements and to the
Engine Manual
for engine
service requirements.
While
Flash Alert
is active, hold the tip of the RESET TOOL (Key Cancel Wand) against the
meter as shown. Within several seconds, the display will stop flashing indicating the Service
Interval has been reset. If the wand gets lost, a small mechanic’s pick-up magnet will work.
