To mow on slopes
WARNING: Read the warning instructions
that follow before you use the product.
• To mow on slopes increases the risk that you can
not control the product and that the product
overturns. This can cause injury or death. It is
necessary to mow carefully on all slopes. If you
cannot reverse up a slope or if you do not feel safe,
do not mow it.
• Remove obstacles such as stones and branches.
• Mow up and down the slope, not from side to side.
• Do not move down a slope with the cutting deck
lifted.
• Do not operate the product on ground that slopes
more than 10°.
• Do not start or stop on a slope. If the tires start to
slip, stop the blades and move slowly down the
slope.
• For model RC 318T, always use the speed brake
pedal for more brake power when you operate on
slopes.
• Move smoothly and slowly on slopes.
• Do not make sudden changes in speed or direction.
10
63 - 007 - 20.06.2017
• Do not turn more than necessary. Turn slowly and
gradually when you move down a slope. Move at low
speed. Turn the wheel carefully.
• Look out for and do not move across furrows, holes
and bumps. There is a higher risk that the product
overturns on ground that is not flat. Tall grass can
hide obstacles.
• Do not mow near edges, ditches or banks. The
product can suddenly overturn if a wheel moves over
the edge of a steep slope or a ditch, or if an edge
gives way. If the product falls into water there is a
risk of drowning.
• Do not mow wet grass. It is slippery, and tires can
lose their grip so that the product skids.
• Do not put your foot on the ground to try to make the
product more stable.
• Move very carefully if anything is attached that can
make the product less stable.

To get a good mowing result
• Do not mow a wet lawn. Wet grass gives inferior
results.
• Start with a high cutting height and lower it gradually.
• Mow with blades that rotate at high speed (highest
permitted engine speed, see
32
). Move the product forward at low speed. If the
grass is not too high and thick, you can get a good
mowing result also at a higher speed.
• We recommend to use the product in collect mode.
To get the best mowing result in non-collect mode,
cut the grass frequently. To cut the grass frequently
does not take more time. The grass is shorter and
you can mow at a higher speed.
• The product can also be used to collect leaves on
the lawn. Set a high cutting height and set the
product in collect mode.

To clean the product
CAUTION: Do not use a high pressure
washer or a steam cleaner. Water can go
into bearings and electrical connections and
cause corrosion which cause damage to the
product.
Clean the product directly after use.
• Before you stop the engine, let the auger run empty
for 10 seconds to clear it from remaining grass.
• Do not clean hot surfaces such as the engine,
muffler and exhaust system. Wait until the surfaces
are cool, then remove the grass or dirt.
• Before you clean with water, use a brush to remove
grass cuttings and dirt from on and around the
transmission, the transmission air intake, and the
engine.
• Use running water to clean the product. Do not use a
high pressure.
• Do not point the jet at electrical components or
bearings. Cleaning additives usually increase the
damage.
• To clean the cutting deck, put it in the servicing
position and hose it down with water.
20 63 - 007 - 20.06.2017
• Hose down the inner surface of the collector with
water.
• Clean the auger in- and outlets.
• When the product is clean, start the product for a
short period to blow off remaining water.
To clean the engine and the muffler
Keep the engine and muffler free from grass cuttings
and dirt. Grass cuttings soaked in fuel or oil on the
engine can increase the fire risk and the risk that the
engine becomes too hot. Let the engine cool before it is
cleaned. Clean with water and a brush.
Grass cuttings around the muffler dry quickly and are a
fire risk. Use a brush or remove the grass cuttings with
water when the muffler is cold.
To clean the engine cooling air intake
Make sure that the engine cooling air intake is not
blocked. Remove grass and dirt with a brush.
To clean the hydraulic oil cooler
Only for RC 320Ts AWD.
Make sure that the hydraulic oil cooling fan is not
blocked and that the area around the hydraulic oil cooler
is clean. Remove grass and dirt with a brush.
To remove blockage from the auger
If the symbol on the auger button is red and the product
beeps continuously, the auger is blocked. The blockage
must be manually removed.
1. Tilt the collector.
2. Pull the auger maintenance tool loose from the
bottom of the collector.
3. Put the auger maintenance tool into the hole at the
top part of the auger.
4. Hold the auger maintenance tool and turn the auger
counterclockwise 5 full turns. The cause of the
blockage is sent down and out of the auger.
5. Pull the auger maintenance tool out and put it back
into the holder on the bottom of the collector.
6. Lower the collector to operating position and start
the engine.
7. If the symbol on the auger button is red and the
product beeps when the engine starts, stop the
engine.
8. Put the cutting deck in servicing position and
manually remove blockage from the auger inlet.
9. Put the cutting deck in mowing position and start the
engine.
10. If the symbol on the auger button is red and the
product beeps when the engine starts, stop the
engine.
11. Let an authorized service agent help you.
Note: When the blockage is removed, the product starts
in non-collect mode and you must select collect mode
again.

To examine the steering wires
The tension of the steering wires can decrease after a
period of time. This causes the adjustment of the
steering to change.
Examine and adjust the steering as follows:
1. The steering wires are correctly tightened if you can
manually move them 5 mm up or down in the groove
on the steering collar.
2. If the wires are too loose, let an authorized service
agent adjust them.

sure the drive belt runs as illustrated below.
7. Put the spring in the spring holder (3).
8. Pull the auger control lever up into operating
position.
9. Attach the front cover.
To do a check of and adjust the cutting deck ground pressure
To get the best mowing results it is important to have
correct pressure from the cutting deck on the underlying
surface.
5. To make sure the support wheels do not bear
weight, put a block between the frame and the
scales.
6. To adjust the ground pressure, turn the adjustment
screws found behind the front wheels on the right
and left sides.

to sharpen them. Tighten the blade bolts with tightening
torque 60 Nm, in the direction of the arrows in the
illustration.
CAUTION: Damaged or incorrectly balanced
blades cause unbalance that can damage
the product. Replace damaged blades. Let
an authorized service agent help you
sharpen and balance blunt blades.
To replace the blades
4. Turn the lift strut to extend the stay or make it
shorter. Extend the stay to lift the rear edge of the
cover. Make the stay shorter to lower the rear edge
of the cover.
63 - 007 - 20.06.2017

9. Tighten the dipstick correctly before you start the
engine. Start and idle the engine for approximately
30 seconds. Stop the engine. Wait 30 seconds and
do a check of the oil level again.
To replace the engine oil
WARNING: Engine oil is very hot directly
after the engine is stopped. Let the engine
become cool before you drain the engine oil.
If you spill engine oil on your skin, clean it
with soap and water.
1. Put a container below the left engine oil drain plug.
2. Remove the dipstick.
3. Remove the drain plug.
4. Clean the oil from the dipstick.
5. Put the dipstick back in and tighten it.

for instructions how to fill oil.
7. Run the engine warm, then make sure that there is
no leakage from the oil plug.
To change the oil filter
1. Turn the oil filter counterclockwise to remove.
63 - 007 - 20.06.2017
2. Lightly lubricate the rubber seal on the new oil filter
with new oil.
3. To attach the oil filter, turn it clockwise by hand until
the rubber seal is in position, then tighten a half turn
more.
4. Fill with new oil as given in
engine oil level on page 28
5. Start the engine and let it idle for 3 minutes.

To do a check of the transmission oil level
1. Remove the two screws, one on each side, and lift
off the transmission cover.
3. Fill with engine oil if the oil level is below the lower
line, but do not fill above the top line. See
data on page 32
and RC 320Ts AWD. RC 320Ts AWD must have a
synthetic oil.
