Chapter 4: Maintenance
58 M47-17035-EN
Hydraulic power supply (HPS)
The HPS should be maintained according to the “Preventative maintenance schedule” on page 52 .
Check the oil cleanliness
The cleanliness of the oil in the reservoir should be checked at the frequency stated in the “Preventative
maintenance schedule” on page 52 . Check the appearance of the oil through the sight gauge; it
should be a clear amber color. If the oil appears dirty, it should be changed (see “Change the oil” on
page 60 ).
Add oil to reservoir
It should only be necessary to add oil to the reservoir if an oil leak is evident or if the oil temperature/level
switch indicates that the level of the oil is below the allowable level. However, the oil level should be
checked at the frequency stated in the
“Preventative maintenance schedule” on page 52 . Check the
oil level through the sight gauge on the HPS. The oil should be to the top of the sight gauge when the
frame’s hydraulic cylinder is fully retracted. When it is necessary to add oil, perform the following
procedure.
Equipment and supplies required
•
A 4 mm hex key (supplied)
•
A clean funnel with a mesh filter
•
Clean towels, rags, or similar
•
Hydraulic fluid (amount required depends on how much is needed to sufficiently fill reservoir), for
fluid specifications see
“Oil type and quantity” on page 63
Recommended procedure
Refer to Figure 12 on page 59 for identification of components.
1. Remove the rear cover from the console. Refer to “Remove and install console covers” on
page 54 .
2. Clean the area around the fill hole and air breather filter (7 and 6) to remove all dust, dirt and grime.
3. If the oil temperature/level switch has tripped and it is determined that the trip was caused by a low
oil level, perform steps b through d of this procedure only. Otherwise, skip this step and continue
with step 4 .
a. Remove the air breather filter from the reservoir fill hole - push down and turn counterclockwise.
b. Insert the clean funnel with a mesh filter into the fill hole and add enough of the recommended
hydraulic fluid to the reservoir until the oil is visible at the bottom of the sight gauge. This will
reset the temperature/level switch.
In the United States and Canada, an oil sample test kit is available for purchase from Instron Services;
contact your local Instron Services department as directed on page
18 for more information about the
test kit.
All equipment and supplies must be supplied by the customer unless noted as “supplied”. For a list of
equipment that was supplied with the system, refer to
“Ancillary parts” on page 64 .
