• Blow the paper dust inside of the vacuum piston and the holes on
the suction head away with compressed air.
• Wipe the piston using a dry cloth. If it is difficult to remove the dirt
on the vacuum piston, wipe with alcohol or kerosene.
CAUTION
Do not lubricate the vacuum pistons.
Any lubricating oil will catch more
paper dust. Do not hit or scratch the
pistons. Keep the suction cups away
from kerosene or oil to prevent them
from deteriorating.
