Training
1. Read the instructions carefully. Be familiar with
the controls and the proper use of the equipment.
2. Never allow children or people unfamiliar with
these instructions to use the lawn mower. Local
regulations may restrict the age of the operator.
3. Never mow while people, especially children, or
pets are nearby.
4. Keep in mind that the operator or user is responsi-
ble for accidents or hazards occurring to other peo-
ple or their property.
5. Do not carry passengers.
6. All drivers should seek and obtain professional and
practical instruction. Such instruction should
emphasize:
• the need for care and concentration when
working with ride-on machines;
• control of a ride-on machine sliding on a slope
will not be regained by the application of the
brake. The main reasons for loss of control
are:
– insufficient wheel grip;
– being driven too fast;
– inadequate braking;
– the type of machine is unsuitable for its
task;
– lack of awareness of the effects of ground
conditions, especially slopes;
– incorrect hitching and load distribution.
Preparation
1. While mowing, always wear substantial footwear
and long trousers. Do not operate the equipment
when barefoot or wearing open sandals.
2. Thoroughly inspect the area where the equipment
is to be used and remove all objects which may be
thrown by the machine.
3. WARNING—Petrol is highly flammable.
• Store fuel in containers specifically designed
for this purpose.
• Refuel outdoors only and do not smoke while
refueling.
• Add fuel before starting the engine. Never
remove the cap of the fuel tank or add petrol
while the engine is running or when the
engine is hot.
• If petrol is spilled, do not attempt to start the
engine but move the machine away from the
are of spillage and avoid creating any source
of ignition until petrol vapors have dissipated.
• Replace all fuel tanks and container caps
securely.
4. Replace faulty silencers.
Operation
1. Do not operate the engine in a confined space
where dangerous carbon monoxide fumes can col-
lect.
2. Mow only in daylight or in good artificial light.
3. Before attempting to start the engine, disengage all
blade attachment clutches and shift into neutral.
4. Do not use on slopes of more than:
• Never mow side hills over 5°
• Never mow uphill over 10°
• Never mow downhill over 15°
5. Remember there is no such thing as a “safe” slope.
Travel on grass slopes requires particular care. To
guard against overturning:
• do not stop or start suddenly when going up or
downhill;
• engage the clutch slowly, and always keep the
machine in gear, especially when travailing
downhill;
• machine speeds should be kept low on slopes
and during tight turns;
• stay alert for bumps and hollows and other
hidden hazards;
Safety

4
• never mow across the face of the slope,
unless the lawn mower is designed for this
purpose.
6. Use care when pulling loads or using heavy
equipment.
• Use only approved drawbar hitch points.
• Limit loads to those you can safely control.
• Do not turn sharply. Use care when revers-
ing.
• Use counterweight(s) or wheel weights
when suggested in the instruction handbook.
7. Watch out for traffic when crossing or near road-
ways.
8. Stop the blades rotating before crossing surfaces
other than grass.
9. When using any attachments, never direct dis-
charge of material toward bystanders nor allow
anyone near the machine while in operation .
10. Never operate the lawn mower with defective
guards, shields or without safety protective
devices in place.
11. Do not change the engine governor settings or
overspeed the engine. Operating the engine at
excessive speeds may increase the hazard of per-
sonal injury.
12. Before leaving the operator’s position:
• disengage the power take-off and lower the
attachments;
• change into neutral and set the parking
brake;
• stop the engine and remove the key.
13. Disengage the drive to attachments when trans-
porting or not in use.
14. Stop the engine and disengage the drive to the
attachment
• before refueling;
• before removing the grass catcher;
• before making height adjustments unless the
adjustment can be made from the operator’s
position.
• before clearing blockages;
• before checking, cleaning or working on the
lawnmower;
• after striking a foreign object. Inspect the
lawnmower for damage and make repairs
before restarting and operating the equipment.
15. Reduce the throttle setting during engine runout and,
if the engine is provided with a shutoff valve, turn
the fuel off at the conclusion of mowing.
Maintenance and Storage
1. Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
2. Never store the equipment with petrol in the tank
inside a building where fumes may reach an open
flame or spark.
3. Allow the engine to cool before storing in any enclo-
sure.
4. To reduce the fire hazard, keep the engine, silencer,
battery compartment and petrol storage area free of
grass, leaves, or excessive grease.
5. Check the grass catcher frequently for wear or dete-
rioration.
6. Replace worn or damaged parts for safety.
7. If the fuel tank has to be drained, this should be
done outdoors.
8. Be careful during adjustment of the machine to pre-
vent entrapment of the fingers between moving
blades and fixed parts of the machine.
9. On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
10. When the machine is to be parked, stored or left
unattended, lower the cutting means unless a posi-
tive mechanical lock is used.

IMPORTANT: These hydraulic fluids are specified to allow
optimal operation of the machine in a wide range of tem-
peratures encountered. The group 1 fluids are a multi-vis-
cosity hydraulic fluids which allows operation at lower
temperatures without the increased viscosity, which is asso-
ciated with straight viscosity fluids.
Note: When changing from one type of hydraulic fluid to the
other, be certain to remove all the old fluid from the sys-
tem, because some brands of one type are not completely
compatible with some brands of the other type of
hydraulic fluid.
IMPORTANT: Use only types of hydraulic fluids specified.
Other fluids could cause system damage.

CHECKTHE PLANETARY GEAR DRIVE
OIL (Fig. 7)
Check the oil if external leakage is noted. Use high-quality SAE
85W-140 wt. gear lubrication as replacement.
System capacity is 47.3 cl.
1. With the machine on a level surface, position the wheel so
the check/drain plug is at either three or nine o'clock posi-
tion.
2. Remove the plug. Oil should be to the bottom of the hole.
3. Add gear oil, if necessary, to bring fluid up to the correct
level and install the plug.
4. Repeat steps 1–3 on the opposite gear assembly.
CHECK REAR AXLE LUBRICANT
The rear axle is shipped from the factory filled with SAE 85W-
140 wt. gear lubrication. Check the level before the engine is
first started and every 400 hours thereafter. Capacity is 2.3 l.
Visually inspect for leaks daily.
1. Position the machine on a level surface.
2. Remove a check plug from one end of the axle and make
sure lubricant is up to bottom of hole. If the level is low,
remove the fill plug and add enough lubricant to bring the
level up to the bottom of the check plug holes.
CHECKTIRE PRESSURE
The tires are over-inflated for shipping. Therefore, release some
of the air to reduce the pressure. Correct air pressure in the front
and rear tires is 103–138 kPa.
IMPORTANT: Maintain even pressure in all tires to assure
a good quality-of-cut and proper machine performance. DO
NOT UNDER INFLATE.
CHECK REEL-TO-BEDKNIFE
CONTACT
Each day before operating, check reel-to-bedknife contact,
regardless of whether the quality of cut had previously been
acceptable. There must be light contact across the full length of
the reel and bedknife (refer to Adjusting Reel to Bedknife in
Cutting Unit Operator's Manual).

IMPORTANT: The fuel system may need to be primed
when a new engine is started for the first time, if it runs
out of fuel or if maintenance is performed on the fuel sys-
tem.
1. Unlatch and raise the hood.
2. Insert a 3/16" hose over the bleed screw and run the other
end into a container to catch the fuel.
3. Loosen the fuel filter/water separator bleed screw (Fig.
15) a few turns. Pump the priming plunger until a steady
stream of fuel comes out of the hole in the bleed screw.
When the fuel stops foaming, tighten the bleed screw dur-
ing the downstroke of the priming plunger. Wipe up any
spilled fuel.
4. Pump the priming plunger until you feel resistance. Try to
start the engine. If the engine does not start, repeat step 3.
Note: It may be necessary to bleed the air out of the fuel line
between the fuel filter/water separator and the injection pump.
To do this, loosen the fitting on the injection pump (Fig. 16)
and repeat the bleeding procedure.
AUTOMATIC CLIP CONTROL
The RM 6700-D is equipped with an electronic controller
which is programmed to achieve automatic clip control. The
machine will automatically adjust the reel speed to attain the
desired clip as the traction speed changes. For the controller to
know what clip is desired, the software must have been prop-
erly set, by your distributor or dealer, to either 5 or 11 blade
and the height-of-cut selector knob must be properly set.
The range of possible reel speeds is a minimum of about 500
RPM and a maximum of about 1400 RPM. As long as the
desired clip requires a reel speed within this range, the
machine will maintain the desired clip. If the traction speed is
too slow or too fast to allow the desired clip, the reel control
light (on the front control panel) will illuminate, warning that
the desired clip is not being maintained. For example, if the
traction speed is zero, the reels will still run at the minimum
speed of about 500 RPM, which will result in a clip smaller
than desired and cause the reel control light to illuminate. The

approximate ranges of traction speed which will result in the
desired clip are as follows for several of the possible heights of
cut:
SELECTING CLIP RATE (REEL SPEED)
To achieve a consistent, high quality of cut, and a uniform after-
cut appearance, the reel speed be matched to the height of cut.
The machine controller is programmed to automatically control
the reel speed to give the correct clip, even as traction speed
changes. To control the reel speed, the controller must know
the height of cut of the machine, and whether the machine is
equipped with 5-, 7-or 11-blade reels.
Adjust the height-of-cut selector knob as follows:
1. Verify the height-of-cut setting on the cutting units. Using
the column of the chart above or the chart under the seat
plate, listing either 5-, 7- or 11-blade reels, find the height
of cut listing nearest the actual height-of-cut setting. Look
across the chart to find the letter corresponding to that
height of cut.
2. Turn the height-of-cut selector knob to the letter setting

determined in step 1.
3. Operate the machine for several days, then examine the
cut to ensure satisfaction with the quality of cut. The
height-of-cut knob may be set one position on either side
of the position on the chart to account for differences in
grass condition, grass length removed, and personal pref-
erence of the superintendent. For a cut with more grass
removed but slightly more clip visibility, move the
height-of-cut selector knob one position higher than spec-
ified. For a cut with less grass removed and slightly less
clip visibility, move the height-of-cut selector one posi-
tion lower than specified.
Full Speed—There may be times when it is desirable for the
reels to run at full speed regardless of the machine’s traction
speed. Examples of this are vertical cutting or heavy scalping.
In such cases, the height-of-cut selector knob may be set to
position "A" which will command the machine controller to
run the reels at full speed at all times.
