Remove the Series 685 Grip Supply Side Panels
Both side panels can be removed to provide better access for maintenance
procedures.
Each side panel is held in place by a screw which is located near the front feet of
the cabinet. These screws are installed to prevent the sides from moving during
shipment. Once they are removed, they need not be reinstalled unless you want to
transport the hydraulic grip supply (see “Preparing the Grip Supply for Transport
or Storage”).
Once the transport screws are removed, the side panels can be lifted and pulled
away from the chassis. The side panels mount to the chassis with slotted tabs that
mate with flanged pins. Each door has four slots.
Clean the Heat Exchanger
Note Cleaning the heat exchanger only applies to the Model 685.10 and
Model 685.22 Hydraulic Grip Supplies.
Clean the heat exchanger every six months.
• If the motor/pump/reservoir assembly is installed in the cabinet,
use a vacuum cleaner tool to remove dust and dirt from the fins of the heat
exchanger.
• If the motor/pump/reservoir assembly is outside the cabinet,
use a vacuum cleaner tool or compressed air to remove dust and dirt from
the fins of the heat exchanger.
Replace the Hydraulic Fluid Filter Element
Note Replacing the hydraulic fluid filter only applies to the Model 685.10 and
Model 685.22 Hydraulic Grip Supplies.
Replace the fluid filter element whenever replacing the hydraulic fluid, or every
six months. The filter is located behind the left side door (see “Component
Identification”).
The fluid filter uses a spin-on filter and may require a strap-type wrench for
removal. The MTS part number for the filter element is 114963-11. Use a drip
pan and rags to catch and wipe up fluid spilled during this procedure.
1. Turn the power switch to the Off position.
Water A milky appearance indicates water is present in
the fluid, usually from condensation.
Sediment Allow the sample to stand overnight, and then
check for sediment. Sediment at the bottom of the
sample indicates a collapsed, ruptured, or clogged
filter.
