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.

SERVICE INFORMATION
1. Check the reservoir level using the sight glass on the top of the tank. If required, add to
reservoir with tractor transmission hydraulic oil (AW or ISO rating of 68 is recommended ).
Recheck oil level after the tiller has been run and oil has been circulated through the tine
motor. Routinely check level thereafter. DO NOT OVERFILL THE TANK.
2. Change the hydraulic oil filterafter the first 50 hours of use. Change it after every 200 hours
thereafter.
3. Check the tine bolts after each use and tighten as needed. Check all hydraulic fittings for
leaks and tighten if necessary.
4. Tines should be changed as often as needed for the machine to do a satisfactory and efficient
tilling job. Use Loctitestud and bearing adhesive/sealant on tine bolt threads to prevent
loosening.
5. The grease zerk on the end of the tine frame should be greased after every 4 to 8 hours of
use.
6. The grease zerks on the wheels should be greased monthly.
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.
