In the case of using a cable reel, always completely unwind the cable from the reel. It is recommended that the mower must be connected to a Residual Current Device (RCD).
Assembly instructions and main adjustments
Some parts of the lawnmower have been dismantled for transport purposes. 2
Knobs, 2 Square bolts, and 2 Limit wire clips are to be found in plastic bags.
Grass lead board, Collect grass assembly, Bracket, and Grass box’s cover are
in the box Assembly is simple if you follow these instructions:
Fitting/Removing/Emptying Grass collector bag
- Insert the handle into the Grass box’s cover (Fig.2-1).
- Assemble the left part and the right part of the Grass box together (Fig.2-2).
- Insert the Grass box’s cover into the Grass box, then turn around (Fig.2-3).
- Hook the Grass box’s cover and the Grass box (Fig.2-4).
- Insert the Grass lead board into the Grass box (Fig.2-5).
- Lift the guard (9) and hold up, and fit the grass-box (16) (Fig.2-9).
- Lift the guard (9) and hold up. Remove grass-box (16).
- For nongrass collection, the mower can be used without the grass-box (8) in position, with the deflector guard (9) in the down position.
Handle
- Rotate the tube (8) and lock the knob (15) (one on each side) (Fig.2-6 and Fig.2-7).
- Note: The tube (8) height is adjustable. Fix handles in the desired position.
- Attach the handle top (1) with bolts and wing nuts (7) to the handle bottom (8) (Fig.2-8).
- Note: for storage purposes, the handle is foldable.
Extension cable / cable restraint (Fig.13)
Connect the female socket of the cable to the male socket of the mower. To
avoid disconnection of the cable during operation, you have to pull it through
the cable restraint.
Tips for mowing
- Start mowing as close as possible to the power socket.
- Always keep the extension lead on the section of the lawn than has already been mown.
- Maintain a constant cutting height of 3 – 5 cm; do not shorten the grass to less than half its original height.
- Do not overload the lawnmower! If the motor speed drops perceptibly due to long, heavy grass, increase the cutting height and mow several times.
- Mow in the morning or late afternoon to prevent the freshly cut grass from drying out.
- During phases of strong growth, mow twice weekly; in periods of low rainfall, increase intervals between mowing accordingly.
Operating Instructions
Connect to the power supply
- Connect the male plug of the cable to the mains power supply (230 -240V – 50Hz).
- Ensure that sufficient cable slack is available.
Starting/stopping your lawnmower (Fig.14)
Starting:
ATTENTION! Better to press the hand and make the front of your lawnmower
up when you turn on it or else it may cause a fire.
Press and hold the safety button (4) (see Fig.2-11) then squeeze the switch
lever (2) towards the handle (see Fig.2-12).
Release the safety button (4).
Stopping:
Release the switch lever
ATTENTION: After switching off, the cutting blade will go on turning for
a few seconds, make sure the blade has come to complete stillness.
CAUTION: Do not rapidly switch off and on.
Adjusting the cutting height
Make sure your machine is switched off and the blade has come to a complete
stillness before adjusting the cutting height.
ATTENTION: The blades continue to rotate for a few seconds after the
machine is switched off, a rotating blade can cause injury.
Your lawnmower is equipped with a central height adjustment system, offering
11 height settings: 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 68mm,
76mm, and 85mm.
Select the cutting height by locking the lever in the desired position (move
lever outward, slide to correct position, move inward to lock it again) (Fig
2-10).
From rear to front, the adjustable height is from 25mm to 85mm.
Remark: For the first cut of the season, a high-cutting position should
be selected.
Adjusting the handle angle (Fig.15)
You can easily adapt the height of the handle.
Release the clamping levers (15) at both sides of the lower handle part,
select the desired height position of the handle by moving it upwards (or
downwards), then re-lock the clamping levers.
This enables you to adapt the handle upright height from 900mm to 1050mm in 3
different positions.
Mowing / Cutting the grass (Fig.16)
Select a cutting height to suit the actual height of the grass. If necessary,
mow the same section several times so that no more than 4cm is removed at a
go.
Place the lawnmower on the edge of the lawn, close to the power supply. Work
away from that point.
Alter the position of the cable at each turn, and move it to the already cut
side.
When mowing, do not make the motor labor too hard. Otherwise, the rotating
speed drops too much, (you will hear that the motor sound changes).
When this occurs stop mowing and adapt the mowing height to a higher position
to avoid damage to your mower.
NOTE: The motor is protected by a safety overload switch
Emptying the grass box
To prevent the ejector opening/blade from becoming clogged and unnecessary
overloading of the motor, empty the grass box once it is full (Fitting /
removing: see above described).
Hours of operation
Observe your national and regional regulations for the protection against
noise which specify hours during which a lawn mower may be operated.
Maintenance Instructions
IMPORTANT – Routine and accurate maintenance is essential for maintaining
original machine safety and performance levels.
Always stop the motor and unplug the main power before doing any repairs or
maintenance.
Only use original spare parts: The use of non-original and/or incorrectly
fitted parts will jeopardize the safety of the machine, and may cause
accidents or injuries for which the Manufacturer is under no circumstance
liable or responsible.
- Wear strong protective gloves before cleaning, maintaining, or making adjustments to the machine.
- You must remove grass and mud from the chassis to prevent it from drying. This will cause problems the next time the lawn mower is used.
- Paint on internal chassis parts may start to flake over time due to the abrasive action of cutting grass. If this happens, you should touch up with rust-proof paint to prevent rusting that could corrode the metal. You can also use a light oil or silicone spray to prevent rust.
- Lubricate the wheel bearings with a suitable lubricant.
CAUTION – DO NOT use a hose pipe or pressure washer to clean the motor.
Water will damage the motor.
Blade Maintenance
Check the blade, in order to obtain a good cut, the blade should always be
sharp and well balanced. At regular intervals, check the tightness of all
nuts, bolts, and screws.
If the blade hits an obstacle check for damage and if the machine vibrates
badly stop the lawnmower and take it to a service dealer.
It is best if all interventions on the blade are done at a specialized center
that has special tools and equipment.
Only original blades must be used on this machine. Given product evolution,
the blades may be replaced in time with others having similarly
interchangeable and operating safety features.
- You MUST always wear gloves to protect your hands from being cut when working with the blade.
- The blade is made of pressed steel, in order to obtain a precise cut, sharpen the blade frequently, typically around every 28 hours of work.
- Following blade sharpening, you must make sure that the blade is always well balanced.
- To remove the blade, unscrew the bolt, check the blade carrier and all components, and replace them if they are worn or damaged.
- Using silicone spray grease, lightly coat the lawn mower blade to prevent possible rusting during storage.
Storage
- Always unplug the machine from the mains for storage.
- To save space during storage, fold down the upper bar.
- Store the machine in a dry condition and out of reach of children and unauthorized persons
Repairs
- Repair work may only be carried out by Service Centres and authorized specialist work- shops.
- To prevent loss of balance, cutting tools and fastening bolts must be exchanged together.
