Sterling Plumbing Harrier 48 - Manual (Page 25)

Lubricate the wheels, pivot points and linkages with engine oil every 25
operating hours.
Apply a good quality medium grease to the inner control cables at the
point of entry and exit from their outer casing.
Drain the fuel by running the engine until the fuel tank is empty and the
engine stops. Remove the spark plug lead and allow the engine to
cool. Turn the mower on its left hand side and ensure that the air clean-
er side of the engine is uppermost.
Firmly grip the end of the cutterblade with the gloved hand and remove
the bolt, spring washer and distance piece securing the cutterblade with
a 9/16” A/F spanner.
To prevent accidents never work on the cutterblade unless the
spark plug lead has been removed. The cutterblade has sharp
edges. ALWAYS wear strong gloves to protect your hands when
working on the cutterblade. DO NOT rotate tools towards the cut-
ting edges to avoid the risk of injury should the tool slip. ALWAYS
use genuine Hayter replacement parts.
The condition of the cutterblade and its mounting arrangement should
be checked regularly for signs of wear or damage. Ensure that the cut-
terblade is not bent or cracked.
A damaged cutterblade that is out of balance will vibrate excessively
and may break. DO NOT use an unbalanced cutterblade.
Regularly check that the bolt securing the cutterblade is tightened to the
specified torque of 54Nm.
Replace the cutterblade every 2 years of sooner if excessively worn or
damaged.
To prevent injury it is wise to seek assistance when turning the mower
on its side.
