4. MAINTENANCE
• Clean after use with warm soapy water being careful not to introduce the
water to the oil in the reservoir through the filler breather.
• When not in use pumps should be stored in a cool dry area free from dust.
•
The air filter should be cleaned
and drained of water frequently both prior
to use and during long periods of use.
•
Change oil after 250 hours use or every 2 years, more frequently in dusty
environments.
• Servicing should be carried
out by a qualified hydraulic technician.
