CONTROLS
Figure 5a (model RM882 & RM982F)
Figure 5b (model RM952)
SPEED CONTROL LEVER (HST)
This lever is used to go forward, reverse and stop the machine (1, Fig 5a & 5b). When the lever is
moved to « R » the machine is going on reverse. When lever is moved from « N » to « F », the
machine is going forward. When lever is located in « N » position the machine is stopped.
Travel speed is increased by pushed the lever from « N » to « F » or « R ». Travel speed is
decreased by push the lever from « F » or « R » to « N ».
Push or release lever gradually (except on an emergency) in order to avoid sudden stop and go.
DANGER
When the travel lever is released to stop the machine, it might be damaged. Release the lever
to « N » gently, except in case of emergency to avoid sudden stops.
THROTTLE LEVER
Push the throttle lever(2, Fig 5a & 5b) forward to increase engine speed, pull the throttle lever
backward to decrease engine speed. The machine is always used at full engine speed to mow.
DIFFERENTIAL LOCK LEVER
This lever(3, Fig 5a & 5b) is used that the rear wheels to be moved together in slipping areas. The diff
lock should be locked when one wheel is slipping. Release the lever as soon as the machine leaves
the slipping area.
The diff lock shoud be used in straight line: never use the diff lock lever when turning.
The damage to the transmission will not be covered by the warranty
SUB CHANGE LEVER (ONLY ON RM952)
This lever control to basic driving speed condition. (4, Fig 5b)
[ ] is Low speed position. [ ] is Hi speed position.
To move the lever, push it completely down then move to the wished position by keeping it pushed
and release it.
For the Grass cutting work, we suggest to use Low speed position to reduce the machine damage.
On the Neutral position (N), HST gearbox is disengaged. It enable to push the machine without
engine power.

The highest position of the lever (1, Fig. 7) is
used as the transport position.
The cutting height is adjustable freely by
pressing the push button (1, Fig 7), and the
lever position is high, the height of cut is high,
when lever position is low, the height of cut is
low.
WARNING
When cutting height lever is in low position, the machine needs strong power, and spread
more thrown objects. Cutting low can cause damage to the machine and injury.

OPERATION
CAUTION
Check the tightening of bolts before use the machine, refering to the tightening torque charts.
The safety was one of our main worry when designing and manufacturing this machine. Therefore,
negligence in the use of the machine should reduce our efforts to nothing. The prevention strictly
depends on the care and on the skill of the user when applying and maintening the machine.The
best safety method remains a careful and skilled user ; we wish you to be this kind of user.
The user of this machine is responsible for its safe use. The user must be a skilled user and specially
trained for the use of the machine. Read and understand the safety instructions. This machine has
been designed to mow grass. It is not designed for any other operation. It is not designed to transport
other tools or materials that might damage it and cause injuries to the user. It must not be used to
carry persons.
Never use the machine without having properly carried out all the maintenance as described in
the daily maintenance chapter.
CAUTION
Never let children or unskilled persons use the machine. Check that nobody or no object
stands near the machine during working. It could be hit by thrown object. Nobody must stand
on the machine except the driver. Never put your hands under moving parts.
STARTING OF THE ENGINE
⚫Turn the fuel cock "ON" and sit down on operator’s seat.
⚫Check that cutting blade are disengaged, cutting height lever is in transport position and the
travel lever is in neutral position « N ».
⚫Pull the choke leverl if the engine is cold. Push the throttle lever to half if the engine is hot.
⚫Press the brake pedal and turn the key in start position. When the engine has started, release the
key and push back the choke lever.
MOWING
•Adjust the cutting height control lever if necessary.
WARNING
Do not forget that it is better to mow grass in several times. Cutting result is clear and efficient.
Remember that the machine is deteriorated rapidly in hot and dry weather. When the cutting height is
low, the blade may hit the ground and it causes damage to the blade. The user and bystanders are
likely to be injured by the thrown object, The thrown object cause damage to their properties.
⚫Push the throttle lever to forward in order to make running speed faster. Then, slowly engage the
cutting blade control lever in mowing position and go forward in the grass to mow.
The best cutting speed depends on quantity and the density of the grass. Usually the machine should
mow between 3 and 8 km/h. A tall grass should be cut slowly and a low grass can be cut faster.

OREC RM881 - © SAT 2021-05-06

CAUTION
It is very dangerous to work in slopes.
Never work in slopes more than 15°(RM882/952) and 20°(RM982F).
WARNING
Check that there is nobody in the mowing area and
especially in the thrown object zone (Figure 10).
Stop the machine immediatly when hitting something. Let
the machine cold and clean. Check the machine or ask

MAINTENANCE
Transmission (gear) oil level (Figure 12)
Check the level with the machine on a flat surface. Oil level
should be lowest of the window(C, Fig 12). If needed, add
oil by this window. Drain oil from plug(A, Figure 12).
Use only SAE 90 or API GL-5. Oil capacity : 1.00L
Transmission oil replacement frequency
First replacement :
After 20 hours
Later replacement :
Each 100 hours or Every year whichever comes first.
HST oil level (Figure 14)
Check HST oil level regularly with the machine on a flat surface. Be sure correct oil level is
maintained. Oil level should reach the upper level "FULL". If needed, add the oil “VG46” or “SAE
10W30”. Refill the same type of oil. Never mix different type of oil.
Oil capacity: 0.50L(RM882/RM952), 5.0L(RM982F).
Check for oil leak.
Rear HST oil replacement (Figure 13,Figure 14)
HST oil is clean when the unit is delivered. But when the unit is used for a long time, the inside of HST
unit will be dirty because there are some sludge and the oil is degraded. And dirty oil might disturb the
smooth working.
Replace HST oil frequently for your safety and smooth working.
Also replace oil filter when HST oil is replaced.
Drain the used oil
1. Place the suitable container below the HST unit to catch the oil, then remove the oil drain plug (1
Figure 13).
2. Allow the used oil to drain completely, then reinstall the oil drain plug, and tighten the oil drain plug
securely.
3. With the HST unit on a flat surface, refill to the upper limit mark with the recommended oil. (Refill
same oil if possible.)
When oil is added, please pay high attention not to mix dust with oil. Tighten the cap securely to
prevent leakage.

Never loose the bolt (2 Figure 13). Otherwise, it might influence for machine driving.
To do so is considered misuse, and damage caused by misuse is not covered by Warranty.
Bleeding the hydrostatic transmission system :
•After replacing the HST oil, some air can go in the
hydrostatic system. If there is air in the transmission
system, the driving is not perfect. Do as following.
•Tilt the change lever by half to FORWARD and
BACKWARD for 10 seconds and then, return the
change lever to neutral position.(Figure 15)
*Repeat aboveoperation 5 times.
When tilt the change lever, throttle must be kept idling.
(Figure 15)
•And then, check if there is no bubbles in the HST oil tank.
After working, check if the oil level reaches "High level position" in oil tank.
If not, add oil up to "High level position" in oil tank.(figure 14)
