Notes on working with the machine

9.1 General points
Risk of injury!
**** Untangle any knots in the cable immediately.
Guide the electric cable behind you when mowing. Electric cables can be inadvertently cut when mowing and present a tripping hazard. They therefore involve a high accident risk. For this reason, mow so that the electric cable is always visible in the area of grass that has already been cut.
To ensure a perfect, thick lawn, mow regularly and keep the grass short.

Do not cut the lawn too short in hot, dry conditions as it will dry out or burn in the sun and become unsightly.
The cutting pattern will be better with a sharp blade than with a blunt one; the blade should therefore be sharpened regularly (STIHLspecialist dealer).

9.2 Correct motor load
Do not switch on the lawn mower in tall grass or at the lowest cutting height.
The lawn mower load must never cause the motor speed to drop significantly.
If the speed drops, select a higher cutting height setting and/or reduce the rate of feed.

9.3 If the mowing blade blocks
Switch off the motor immediately and disconnect the mains plug. Then eliminate the cause of the fault.

9.4 Thermal motor overload protection
If an overload of the motor occurs during operation, the built-in thermal overload protection device automatically switches off the motor.
Causes for an overload:

• mowing excessively high grass or cutting height adjusted too low,
• excessive rate of feed,
• inadequate cleaning of the cooling air guide (inlet slots),
• mowing blade is blunt or worn,
• unsuitable or excessively long electric cable – voltage loss (⇒ 11.1).

Recommencing operation
Resume normal operation of the machine following a cooling period of up to 10min (depending on the ambient temperature) (⇒11.).

Safety devices

The machine is equipped with several safety devices for safe operation and for the prevention of improper use.
Risk of injury!
If a safety device is found to be defective, the machine must not be operated. Consult a specialist dealer; STIHL recommends STIHL specialist dealers.

10.1 Safety devices
The lawn mower is equipped with safety devices, which prevent inadvertent contact with the mowing blade and with ejected clippings.
These include the housing, discharge flap, grass catcher box and correctly installed handlebar.
10.2 Two-hand operation
The motor can only be switched on by pressing and holding the ON button with the right hand and then pulling the motorstop lever to the handlebar with the left hand.
10.3 Motor run-down brake
When the motorstop lever is released, the mowing blade comes to a complete standstill in less than threeseconds.
An integrated motor run-down brake shortens the run-down time until the blade stops.

Operating the machine

11.1 Electrical connection
Danger of electric shock!
Observe the safety instructions in the section “For your safety” (⇒4.8).
If using a cable drum, the connection cord must be unwound completely, otherwise electrical resistance may cause loss of power and overheating.
Only electric cables which are no lighter than rubber sheathed cables H07RNFDIN/VDE0282 may be used as electric cables.
Minimum cross-section:
up to 25m length: 3×1.5mm²
up to 50m length: 3×2.5mm²
The connectors of the electric cable must be made of rubber or have a rubber cover and conform to the standard DIN/VDE0620.
The mains voltage and mains frequency must correspond to the information on the rating plate and the information contained in the section “Technicalspecifications” (⇒18.).
The power cable must be adequately protected by fuse (⇒18.).
This machine is intended for operation with a power supply having a system impedance of Z max at the transfer point (house connection) of maximum 0.49Ohm (at 50Hz).
The user must ensure that the machine is only operated with a power supply which meets this requirement. If necessary, this information can be obtained from the local electric power company.

11.2 Strain relief
11
During working, the strain relief prevents any unintentional disconnection of the electric cable and any resulting damage to the mains connection on the machine.
For this reason, the electric cable must be fed through the strain relief.

• Form a loop in the power cable (1) and guide it through the opening (2).
• Then push the loop over the hook (3) and pull it tight.

11.3 Switching on the lawn mower
12
Do not start the motor in high grass or when the mower is set to the lowest cutting height, as this makes switching on difficult.

• Press and hold down the ON button(1). Pull motorstop lever(2) to handlebar and hold.
• The ON button(1) can be released once motorstop lever(2) is pressed.

Maintenance

12.1 General
Risk of injury!
Observe the safety instructions in the section “For your safety” (⇒ 4.).
Annual service by the specialist dealer:
The lawn mower should be inspected once annually by a specialist dealer. STIHL recommends STIHL specialist dealers.

12.2 Cleaning the machine
Maintenance interval:
After each use
16

• Only clean the machine using water, with a brush or with a cloth. Remove accumulated clipping deposits using a stick. If necessary, use a special cleaner (e.g. STIHL special cleaner).
• Never spray water or high pressure cleaners onto switches, motor components, seals or bearing points.

Risk of injury!
Before tilting the mower, place it on firm, level, flat ground. The machine may tip over when working on it in the cleaning position. Always stand to the side of the machine. Never work in front of or behind the mower.
To facilitate cleaning work, it is recommended to select the highest cutting level before placing the machine in the cleaning position.
Cleaning position RME 443:

• Detach the grass catcher box. (⇒8.3)
• Hold the upper handlebar(1) and open the quick-clamping devices – fold downwards.
• Set down upper handlebar(1) rearwards.
• Open discharge flap(2) and hold it open.
• Lift up the machine at the front and place in the cleaning position as shown. Check that the machine is stable.

Cleaning position RME443C:
Danger of pinching!
After actuation of the detent lever, the upper handlebar can fall to the lowest position under its own weight.
Never place your finger between the handlebar and the handlebar console (under the detent lever).

• Detach the grass catcher box. (⇒ 8.3)
• Open discharge flap (2) and hold it open.
• Press the detent lever (3) downwards with the thumb and hold.
• Hold the machine at the front handleand tilt it slowly rearwards.
• Release the discharge flap (2) and check that the machine is standing securely.

12.3 Electric motor and wheels
The electric motor is maintenance-free.
The wheel bearings are maintenance-free.

12.4 Upper handlebar RME443
Maintenance interval:
Before each use
The upper handlebar is coated with a insulating layer. Should this layer become damaged, the upper handlebar must be replaced.

12.5 Mowing blade maintenance
17

Maintenance interval:
Before each use

• Tilt the mower upwards into the cleaning position. (⇒12.2)
• Clean the mowing blade(1) and check it for damage (notches or cracks) and wear; replace if necessary.
• Use a slide calliper (not included in standard equipment) to measure blade thickness at 5points at least. In particular, the minimum thickness must also be ensured in the area of the blade wings.
• Place a ruler(2) against the front blade edge and measure permissible grinding.

Risk of injury!
A worn or damaged mowing blade may break off and cause serious injuries. The instructions for blade maintenance must therefore always be observed.
Blades are subjected to differing degrees of wear depending on the location and duration of use. If you use the machine on sandy ground or use it frequently under dry conditions, the blade will be subjected to greater loads and will wear more quickly than the average.

Wear limits:
Distance A:
The cutting edges may not be ground back by more than 15m m .
Distance B:
The minimum width of the mowing blade must not be less than 39mm.
Distance C:
The blade thickness must be at least 2 mm at any point.
The check should be performed using a slide calliper.
If the supplied standard blade is not installed in the lawn mower, but e.g.the multi-blade, which is available as a special accessory, different wear limits apply.

12.6 Removing and installing the mowing blade
18
In order to prevent damage to the blade fastening screw, use a suitable 22mm hexagon socket (not included in standard equipment).

1. Removing:
   ● Use a suitable wooden block (1) to counterhold the mowing blade (2).
   ● Tighten the blade fastening screw (3). Remove the mowing blade (2) and blade fastening screw (3).

2. Installing:
   Risk of injury!
   The mowing blade(2) must only be installed as shown. The tabs(6) must face downwards (to the lawn) and the curved wings must point upwards (to the machine).
   Observe the specified torque of 10-15N m when tightening the blade fastening screw, as the secure attachment of the cutting tool depends on this. Additionally secure the blade fastening screw(3) with Loctite243. The blade fastening screw (3) must be replaced each time the blade is replaced.

• Clean the blade contact surface and blade bushing.
• Fit the mowing blade (2) onto the blade bushing with the curved edges pointing upwards. Locating lugs(4) must be located in bores(5) of the mowing blade.
• Use a suitable wooden block (1) to counterhold the mowing blade (2).
• Screw in the blade fastening screw (3) and tighten to a torque of 10-15 Nm.

12.7 Sharpening the mowing blade

Risk of injury!
Check blade for damage before installing. The blade must be replaced if notches or cracks are identified, if the blade is worn back by more than 15mm, or if the blade is thinner than 2mm at any point (⇒ 12.5).
STIHL recommends having the mowing blade sharpened by a technician.
Operation of the machine is impaired in the case of an incorrectly sharpened blade (incorrect sharpening angle, imbalance etc.).
Sharpening instructions:

• Remove mowing blade (⇒ 12.6).
• Cool the mowing blade when sharpening, e.g.with water. The blade must not be allowed to display blue colouring, as this would reduce its cutting quality.
• Sharpen the blade evenly to prevent vibrations due to imbalance.
• Observe sharpening angle of 30°.
• After sharpening, remove any sharpening burr at the cutting edge using fine sandpaper if necessary.

12.8 Storage (winter break)
Store the machine in a dry and locked place that is generally free of dust. Make sure that it is kept out of the reach of children.
Only store the lawn mower in good operating condition, fold down the handlebar if necessary.
Keep all nuts, pins and bolts tightly fastened, replace danger signs and warnings on the machine that have become illegible, check the entire machine for wear and damage. Replace all worn or damaged parts.
Any machine faults must be completely remedied prior to storage.
Note the following points when storing the lawn mower for long periods (winter break):

• Clean all external parts of the machine with care.
• Thoroughly lubricate/grease all moving parts.

Transport

13.1 Transport
19
Risk of injury!
Observe the section “For your safety” before transporting. ( ⇒4.)
Always wear suitable safety clothing when transporting (safety shoes, thick gloves).
Always disconnect the power cable before lifting or transporting. For safety reasons, STIHL recommends lifting or carrying the machine only with the aid of a second person.
Before lifting, note the weight indicated in the section “Technical specifications”.
Carrying the machine:

• Two persons:
  Only hold the machine at the front handle (1) and at the handlebar (3). Always ensure sufficient distance between the mowing blade and your body, particularly your feet and legs.
