PREVENTATIVE MAINTENANCE INSTRUCTIONS
KZN-HYD3(R), KZN-HYD4(R) & KZN-HYD6(R)PUMPS
Always be sure to use only clean filtered hydraulic oil to drive the hydraulic motor. Your
hydraulic system should have a filter and it should be rated at 10 micron.
When connecting hydraulic hoses to the pump, be sure to keep hose connections
clean.
Use hydraulic oils with anti-wear additives such as these recommended oils or their
equivalent:
Pennzoil AW46 Hydraulic Oil
Texaco Rando HDAZ
Shell Tellas Hydraulic Oils
Mobil D.T.E. 20 Series
Chevron EP Hydraulic Oils
Exxon Univis N Hydraulic Oils
Note: When using this equipment in environmentally sensitive areas we recommend
using a bio-degradable oil such as Chevron Clarity, Exxon Univis Bio 40 or Mobil EAL
224H.
Check oil level in the seal chamber every 250 hours and when beginning a new job.
The level should be at the spill point of the fill plug. Do NOT over-fill!
Change oil in seal chamber every 1000 hours Use clean hydraulic oil or non-detergent
10W or 20W motor oil.
Slight discoloration of the oil in the seal chamber is normal. This is due to the wearing
of the mechanical seals.
Presence of water or emulsified oil in the housing indicates immediate need for seal
replacement and inspection of bearings.
