Maintenance for 4128-005 and 4128-555 pumps
Lubrication
DO NOT
USE PETROLEUM/OIL OR
PROPELLANT BASED PRODUCTS
The pump requires very little maintenance but it is recommended that every 3 months the
inner tube should be lubricated using the silicone grease provided
Raise the pump to the top of its stroke and squeeze out a small quantity
of grease.
Smear the grease around the tube and slide the outer tube up and down
a few times to evenly distribute it. Use only a small amount of grease at
any one time.
Do not use any other type of silicone grease on the pump. Replacement
tubes are available from Hill (see website)
