BVA Hydraulics P240L - Manual (Page 5)

MaIntEnancE
1. Inspect hoses and connections daily. Replace damaged
components immediately with BVA Hydraulics
Replacement Parts only.
2. Tighten connections as needed. Use pipe thread sealing
compound when servicing connections.
3. Use only good quality hydraulic fluid. We recommend
Mobil DTE 13M or equivalent. never use brake fluid,
transmission fluid, turbine oil, motor oil, alcohol,
glycerin etc. Use of other than good quality hydraulic
oil will void warranty and damage the pump, hose, and
application.
adding Hydraulic Fluid (refer to Fig. 3)
1. Depressurize and disconnect hydraulic hose from
application.
2. With pump in its upright, horizontal position, remove oil
filler screw located at the rear end cap.
3. Add appropriate hydraulic fluid until level with oil filler
hole.
4. Wipe up any spilled fluid and reinstall the oil filler
screw.
