* Check Carbon Brushes •
Note: See the individual machine system sections for maintenance information.
* Have Nilfi sk-Advance:
Check vacuum motor carbon brushes (Qty 2) once a year or after 300 operating hours.
Check brush motor carbon brushes (Qty 4) once a year or after 500 operating hours.
Note if the vacuum or brush motor brushes are 9.5mm (3/8 inches) or shorter, replace them.
Check wheel drive motor carbon brushes every 500 operating hours. The original length of each brush is 20mm (25/32 inches). Replace when
shorter than 9.5 mm (3/8 inches) to obtain the same motor effi ciency as a new brush.
WARNING!
Turn the key switch off, set the parking brake and disconnect the battery before servicing the machine.
LUBRICATING THE MACHINE
Once a month, pump a small amount of grease into each grease fi tting on the machine until grease seeps out around the bearings.
Grease fi tting locations are:
• Squeegee Wheel Axle
• Steering Wheel Shaft Universal joint
Once a month, apply light machine oil to lubricate the:
• Steering Chain
• General Pivot Points For the Squeegee, Brush Linkage and Side Skirts
• Squeegee mount angle adjustment knob threads
BATTERIES AND CHARGERS
Attention: See the electrical system manual section for battery installation and charger system requirements.
WHEEL DRIVE MOTOR GREASE SPECIFICATION
If drive motor gear housing grease replacement is needed when repair services are performed (Example inspection shows grease contamination).
Clean gear sets and housing and re-pack. Use a multi-purpose, high melting point Lithium based grease, containing additives to provide anti-oxidant,
anti-corrosion and good lubricity properties. Use a total quantity of 4.9-5.6 oz. (140-160g) of grease to service gear case.
The grease to be used must have excellent mechanical stability, water resistance and high load carrying capacity. The MR 158 grease is particularly
recommended for automotive applications including wheel-bearing lubrication. Available NLGI consistency 3.
