Adjusting the blade (See Fig. O & R)
The blades are correctly adjusted when the cutting cylinder (reel) lightly brushes the bottom blade (bed knife)
across the full width as the cylinder is turned. The blades act like a pair of scissors. As a test, correctly adjusted
blades will cut a piece of good quality writing paper (80g/m
2
) across the width of the blade.
The cutting cylinder (reel) should only be adjusted if the grass is not cut cleanly and evenly.
To set blades correctly on cut:
1. Tilt the mower back and wedge securely.
2. Remove the grass bag.
3. Check the cleanness of cut with paper across the cutting width.
4. Turn the adjuster screws clockwise with a flat bladed screwdriver a little at a time and check the cleanness
of cut with a piece of paper as you go along. It may be necessary to only adjust one side to get a nice
scissor action.
Note: setting the blades with heavy contact can cause damage to your mower!
Best practices to reduce noise and vibration
Forcing the mower to cut longer grass than intended or setting it to work at great depths may cause higher vibration
and noise levels. Make sure the cylinder (reel) is accurately ground to reduce vibration. Setting minimal contact
between the cylinder (reel) and bottom blade (bed knife)
is critical to help reducing noise emissions (see “Adjusting
the blade” section). Damaged belts or loose guards can increase noise emissions. Therefore, periodically inspect
the mower for signs of wear and ensure the guards are securely attached and in good condition.
Changing a UC lawn care cartridge (See Fig. P)
The mower is fitted with a
UltraChange™ (UC) cartridge which can be removed and taken to an approved service
agent for sharpening.
To remove a cartridge:
1. Remove the grass bag and battery
2. Pivot the two cartridge clamps (4) upwards away from the machine
3. Press the release lever on the cartridge securing lever (7), then pivot it towards the rear of the machine
until the latch pin locates in upper slot.
4. Pull the cartridge unit out using the handle
To insert a cartridge:
1. Make sure the cartridge clamps are pivoted upwards (4) and cartridge securing lever (7) is pivoted towards
the rear of the machine
2. Hold the cartridge unit by the handle and slide it into the mower. There are a pair of guides either side of
the chassis to help locate it correctly
3. Pivot the cartridge clamps (4) downwards towards the machine
4. Press the release lever on the cartridge securing lever (7) then pivot towards the front of the machine until
the latch pin locates in lower slot. This is tensioning the belt so needs to be done quite firmly
