MultiSystem

STIHL RL-MM - 469BA028 KN

In the STIHL MultiSystem, various MultiEngines and MultiTools are combined to form a machine. In this Instruction Manual, the functional unit of MultiEngine and MultiTool is referred to as a machine.

Accordingly, the instruction manuals for the MultiEngine and the MultiTool constitute the entire Instruction Manual for the machine.

Always read both manuals carefully before using your machine for the first time and keep them safe for future reference.

Therefore, some changes, modifications and improvements may not be covered in this manual.

Safety Precautions and Working Techniques

Special safety precautions must be observed when working with the aerator because its pointed and sharp-edged blades rotate at high speed.
STIHL RL-MM - ManualAlways read and and make sure you understand both instruction manuals (MultiEngine and MultiTool) before using your power tool for the first time and keep them in a safe place for future reference. Non- observance of the safety precautions may result in serious or even fatal injury.

Lend or rent your power tool only to persons who are familiar with this model and its operation -­ do not lend of rent your power tool without the MultiEngine and MultiTool instruction manuals.

Use the power tool only for aerating lawns and similar grassed areas.

Do not use your power tool for any other purpose because of the increased risk of accidents.

Only use attachments and accessories that are explicitly approved for this power tool model by STIHL or are technically identical. If you have any questions in this respect, consult a servicing dealer.

Use only high quality tools and accessories in order to avoid the risk of accidents and damage to the machine.

STIHL recommends the use of original STIHL replacement parts, blades and accessories. They are specifically designed to match the product and meet your performance requirements.

The deflector on this power tool cannot protect the operator from all objects thrown by the attachment (stones, glass, wire, etc.). Such objects may ricochet and then hit the operator.

Never attempt to modify your machine in any way since this may increase the risk of personal injury. STIHL excludes all liability for personal injury and damage to property caused while using unauthorized attachments.

Do not use a pressure washer to clean your power tool. The solid jet of water may damage parts of the power tool.

Transporting the Power Tool

STIHL RL-MM - 469BA001 KN

Always shut off the engine.

Carry your power tool by the handle, attachment in front of you.

Do not touch hot parts of the machine since burn injury will result.

Transporting by vehicle: Properly secure your power tool to prevent turnover, fuel spillage and damage.

Before Starting

Check that your power tool is properly assembled and in good condition ­ refer to appropriate chapters in the MultiEngine and MultiTool instruction manuals.
-­ Blade correctly and securely mounted and in good condition (clean, move freely, not warped).
-­ Inspect the deflectors for damage and wear. Do not operate the machine with a damaged deflector ­ replace damaged parts.
-­ Never attempt to modify the controls or safety devices in any way.
-­ Keep the handles dry and clean ­- free from oil and dirt ­- for safe control of the power tool.
-­ Swing the bike handle to the normal operating position and tighten it down firmly with the rotary knob. See chapter on “Adjusting the Handlebar” in the MultiEngine instruction manual.

To reduce the risk of accidents, do not operate your power tool if it is damaged or not properly assembled.

Check correct position of gearbox and adjust if necessary. This helps reduce the risk of injury from the MultiTool rotating in the wrong direction.

See also notes on “Mounting the MultiTool”.

STIHL RL-MM - MultiTools 1

If you use metal tools, position the gearbox so that the axle is below the drive shaft.

Use for:
-­ BF-MM pick tines
-­ BK-MM bolo tines
-­ FC-MM edger
-­ RL-MM aerator
-­ MF-MM dethatcher

Holding and Controlling the Power Tool

Make sure you always have good balance and secure footing.

STIHL RL-MM - 469BA045 KN

Always hold the power tool firmly with both hands on the handles.

Right handle on control handle, left hand on left handle.

During Operation

In the event of impending danger or in an emergency, switch off the engine immediately by moving the slide control / stop switch / button to 0 or STOP.

STIHL RL-MM - Operation

To reduce the risk of injury from contact with the tool and thrown objects, do not allow any other persons within a radius of 5 meters of your own position. To reduce the risk of damage to property, also maintain this distance from other objects (vehicles, windows).

The correct engine idle speed is important to ensure that the attachment stops moving when you let go of the throttle trigger. Check and correct the idle speed setting regularly. If the attachment still rotates when the engine is idling, have your dealer check your machine and make proper adjustments or repairs ­- see MultiEngine instruction manual.
STIHL RL-MM - Symbol 5 The gearbox becomes hot during operation. To reduce the risk of burn injury , do not touch the gearbox housing.
To reduce the risk of injury from thrown objects or contact with the attachment, never operate the unit without a properly mounted deflector designed specifically for the unit and the attachment.

Always stand behind the deflector or to one side of the machine during operation ­- never in front of the attachment.

Take special care in slippery conditions.
– damp or ice on slopes or uneven ground.

To reduce the risk of accidents or injury,
remove all obstacles and objects from the work area.

Inspect the work area ­- solid objects (stones, pieces of metal, etc.) may damage the attachment.

STIHL RL-MM - Symbol 6 To avoid the risk of electric shock , never use your power tool in areas where electrical lines are laid on the surface or buried just below the surface. Striking and damaging such lines with the attachment could cause serious or even fatal injury.

Operate your power tool at normal walking pace only.

Be extremely cautious when pulling the power tool towards you because of the risk of injury from contact with the rotating attachment.

Make sure you always have good balance and secure footing.

Be extremely cautious when changing direction with the power tool ­ especially on slopes.

On slopes, always work parallel to the gradient to reduce the risk of injury from slipping or contact with the attachment.

Never work on steep slopes because of the risk of injury through loss of control of the power tool.

Take particular care when working close to fences, walls, stones, roots, trees and areas of dense growth. Solid objects may be thrown in your direction or damage the attachment ­ – risk of accidents.

When working next to high scrub, bushes and hedges, take care not to harm small animals.

Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.

To reduce the risk of accidents , take a break in good time to avoid tiredness or exhaustion.

Work calmly and carefully -­ in daylight conditions and only when visibility is good. Stay alert so as not to endanger others.

If your power tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work -­ see also “Before Starting”. Make sure the safety devices are working properly. Do not continue operating your power tool if it is damaged. In case of doubt, consult your servicing dealer.

Do not touch the attachment while the engine is running. If the attachment becomes jammed by an obstruction, switch off the engine immediately before attempting to remove the obstruction.

Opening the throttle while the attachment is blocked increases the load and reduces engine speed. The clutch then slips continuously and this causes overheating and damage to important components (e.g. clutch, polymer housing components) -­ and this can increase the risk of injury from the cutting attachment moving while the engine is idling.

Check the attachment at regular short intervals during operation or immediately if there is a noticeable change in behavior:
-­ Shut off the engine, hold the unit securely.
-­ Check condition and tightness, look for cracks.
-­ Replace damaged working tools immediately, even if they have only superficial cracks.

Clean the attachment and deflector at regular intervals during operation.
-­ Stopping the Engine
-­ Wear gloves.
-­ Remove grass, weeds, clumps of soil, etc.

To reduce the risk of injury, shut off the engine before changing attachments.

Do not continue using or attempt to repair damaged or cracked cutting attachments by welding, straightening or modifying the shape (out of balance).

After Finishing Work

After finishing work or before leaving the unit unattended: Shut off the engine.

After finishing work, clean dirt, soil and plant residue off the attachment ­- wear gloves to reduce the risk of injury.

Do not use grease solvents for cleaning.

After thoroughly cleaning, coat metal surface of attachments with a corrosion inhibitor.

Maintenance and Repairs

Service the machine regularly. Do not attempt any maintenance or repair work not described in the MultiTool and MultiEngine instruction manuals. Have all other work performed by a servicing dealer.

STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. STIHL dealers are regularly given the opportunity to attend training courses and are supplied with the necessary technical information.

Only use high-quality replacement parts in order to avoid the risk of accidents and damage to the power tool. If you have any questions in this respect, consult a servicing dealer.

STIHL recommends the use of original STIHL replacement parts. They are specifically designed to match your model and meet your performance requirements.

To reduce the risk of injury, always shut off the engine before carrying out any maintenance or repairs or cleaning the machine.

Using the Unit

STIHL RL-MM - 482BA001 KN
