note:
only fully qualified personnel should attempt maintenance or repairs.
6.1.
When not in use, the beam should be stored in the lowest position, to minimise corrosion.
6.2.
Keep the beam clean and lubricate all moving parts on a regular basis
WaRning: DO nOT
use brake fluid, or any fluid other than a good quality jack oil, such as SeAleY HYdRAUlIC JACK oIl, as this may
cause serious damage to the jack and will invalidate the warranty!
6.3.
To check on fluid level and to top up, jack the beam up so that the vent valve (see Fig.2) can be accessed and removed . lower the
beam fully and then check on the fluid level either directly or using a dipstick. The level should be just below the vent, top up as
necessary and
DO nOT
overfill as this will affect the smooth operation of the beam. Replace the vent valve.
6.4.
Before each use check for broken, cracked, bent, or loose parts, or any visible damage to pump, saddles, lifting arms, frame and all
parts including nuts, bolts, pins and other fasteners. If any suspect item is found, remove beam from service and take action to
remedy the problem.
DO nOT
use the beam if it is believed to have been subjected to abnormal load or shock load. Inspect and take
appropriate action.
6.5.
Periodically check the pump piston and the ram for signs of corrosion. Clean exposed areas with a clean oiled cloth.
