CAUTION: PERSONAL INJURY
Only proceed when the engine is not running and is at
a low temperature in order to avoid the risk of burns.
1. Open both the pressure caps on the expansion tank(1)
and the filler cap to the radiator (2).
2. Open all drain points. Drain the coolant from the
radiator and engine block, using the drain hose. The
drain nipples are situated under the radiator on the
right side of the engine block.
3. Check that all coolant drains out. Deposits may be
found inside the drain plug/tap, and need to be
cleared away. There is otherwise a risk that the coolant
could remain and cause frost damage. Check whether
the installation has any further taps or plugs at the
lowest points of the cooling water pipes.
4. Close any taps and check that the spring-loaded
covers on the nipples close completely. Install the
rubber plugs and the filler cap(s).
MAINTENANCE
WARNING
Before preforming any maintenance, lock out the unit,
ensuring it cannot automatically start. Failure to do
so could result in equipment damage and/or personal
injury.
CHANGING THE OIL
CAUTION: PERSONAL INJURY
Only change oil when the engine is not running and
is at a low temperature in order to avoid the risk of
burns.
WINCO recommends our 5W-40 fully synthetic heavy duty
engine oil to give you maximum cold weather protection
while maintaining excellent performance in warmer
weather. We have partnered with a national lubrication oil
manufacturer to give you access to Winco private branded
premium oil available at comparable prices to conventional
oils. See your dealer for additional information.
WINCO has plumbed an oil drain valve to the outside of the
unit. Attach a customer supplied 3/4” hose to conveniently
run the oil to a drip pan or suitable container for catching
the oil.
1. Connect the drain hose to the oil drain pump and
check that no leakage can occur.
2. Pump the oil out (or remove the bottom drain plug
and drain the oil).
3. Remove the drain hose (or install the bottom drain
plug).
4. Fill with engine oil.
CHANGING OIL FILTER
The filter must be replaced when the lubricant oil is
changed.
Only use filters with a filtering degree equal to the original
filter.
CAUTION: PERSONAL INJURY
Only change oil when the engine is not running and
is at a low temperature in order to avoid the risk of
burns.
