ENGINE MAINTENANCE
Engine Oil Level Check
The engine oil level should be checked daily. It is recommended that the oil be checked
just before the engine is started for the rst time for that day. The oil level should be
between the ‘Add’ and the ‘Full’ marks on the dipstick.
Do not operate the engine with the oil level below the bottom of the ‘Add’ mark on
the dipstick, or above the top of the ‘Full’ mark.
Adding Engine Oil
It is normal to add some oil in the period of time between oil changes. The amount will
vary with the severity of operation. When adding or replacing engine oil, be sure the oil
meets or exceeds the recommended specication.
Changing Engine Oil and Filter
The engine oil and lter must be changed every 50 hours or every 3 months whichever
occurs rst. The oil and lter should be changed more often if the engine is operating in
dusty or extremely dirty areas, or during periods of high ambient temperature.
Engine Oil Quality
To achieve proper engine performance and durability, it is important that you use only
engine lubricating oils of the correct quality in your engine. Proper quality oils also provide
maximum efciency for crankcase ventilation systems, which reduces pollution.
Use only engine oils displaying the American Petroleum Institute (API) “starburst”
certication mark ‘FOR GASOLINE ENGINES’ on the container.
Engine Oil Recommendation
While multi-viscosity oils are generally recommended, SAE 5W-30 synthetic is specically
recommended year round for your Boxxer 423s engine.
OVERALL MACHINE MAINTENANCE
Maintenance, troubleshooting and repair are much easier tasks to accomplish on a clean
truckmount. Regular cleaning of the truckmount offers the user an opportunity to visually
inspect all facets of the truckmount and spot potential problems before they occur. In
addition to the operational maintenance the following “housekeeping” duties should be
performed.
After each job
• Check the recovery tank and the recovery tank lters. Empty and clean as
necessary.
Daily
• Wipe the truckmount down thoroughly with a damp cloth.
• Wipe down the vacuum and high pressure hoses as needed.
• Inspect and clean the vacuum slot on the cleaning wand.
• Check the wand head for sharp edges that could tear carpet. File down as needed.
• Clean the wand to maintain original appearance.
• Visually inspect the hoses for abrasions, cuts, etc. Repair or replace as needed.
Weekly
• Empty the chemical container. Wash out thoroughly to remove any chemical buildup.
• Inspect the chemical feed line strainer and use solution of equal parts white vinegar
and water to remove any chemical buildup.
• Thoroughly clean the wand and inspect for clogged jets, debris in vacuum slot and
leaking ttings at valve.
• Thoroughly clean the vacuum and high pressure hoses including quick releases and
cuffs.
