WARNING: Always exercise extreme care when performing engine service work. Refer to and understand the
safety guidelines presented on page 3. Additionally, some engine components have sharp edges which could
cause cuts if not handled properly. Wear hand protection. Further, some engine components are heavy. As such,
wear foot protection to protect from accidental drops of engine components. Always use proper form and
procedures when lifting engine components. Ask for help or assistance if in doubt concerning the lifting or
manipulation of the engine or engine components. The use of compressed air is required for some operations.
Compressed air can be dangerous. Do not direct compressed air towards yourself or others. Do not allow bearings
to spin while drying with compressed air. The use of cleaning solvents is also required for certain service
operations. When “SOLVENT” is recommended, a commercially available, low-toxicity, degreasing solvent such
as “SAFETY-KLEEN” should be used. Wear hand and eye protection and avoid direct contact with solvents.

AIR RESTRICTION SWITCH
LDW FOCS diesel engines that are supplied with engine mounted, panel type air
filters as shown above, are fitted with an air filter restriction switch. The purpose of
the air restriction switch is to signal the engine operator, via a lamp or otherwise, of
a high air filter restriction condition. The electrical connections for the signal is
provided at (2) as shown. Following a signal from the restriction switch, the switch
must be reset. Reset the switch by pushing button (1) until the button latches. The
restriction switch is set to 600/650 mm-H

After the restriction signal, the air filter should be replaced at once. Do not clean
the air filter element. Operation in a high restriction condition could cause
excessive oil consumption, low power output, engine overheating and potentially
engine damage.

Service Instructions: Check the sealing rings regularly. Replace the sealing rings if
hardening or damage is noted. Inspect the air filter housing and bowl- replace if
damaged. Carefully clean the reservoir bowl and both elements with clean diesel
fuel. Blow the lower element dry with compressed air. Dry the upper element by
squeezing out excess diesel fuel, then drying with suitable cloths. Fill the reservoir
with clean engine oil to the reference mark. DO NOT OVERFILL.
