Parking Brake - Manual Release
The parking brake is a SAHR - Spring Applied Hydraulic Re-
leased brake. In case of a breakdown or a malfunction of the
hydraulic system, the parking brake can be released by using a
manual high pressure hydraulic pump that must be connect-
ed to the axle parking brake ports ( Figure 3).
NOTE: The minimum release pressure is 435 psi. The maxi-
mum release pressure is 653 psi.
NEVER perform this procedure with the engine running. The
Ignition Switch should be in OFF position, the Parking Brake
ON (engaged) and the red cover over the parking brake
switch CLOSED.
Block all four (4) wheels. Failure to do so could result in
death or serious injury from Telehandler roll away.
1. Block all four wheels to prevent the Telehandler from
moving once the parking brake is disabled.
2. Position the towing vehicle in place. Attach any chain
needed to secure the disabled Telehandler.
3. Locate the two (2) parking brake hydraulic connection
ports as shown in Figure 3.

4. Remove the hydraulic hose connected to one port
5. Connect a manual HP hydraulic pump to the parking
brake ports using a threaded coupling (9/16" - 18 UNF)

and a collector bottle, as shown in Figure 4.
6. Apply hydraulic pressure using the manual hydraulic
pump to release the brake.
NOTE: For illustration purposes, we used an Enerpac P 142
manual HP pump.
Figure 4. Connect HP Pump to HP Parking Brake Ports (both sides of
axle). See Figure 3 For Ports Location.
7. To reapply parking brake, disconnect the manual hydraulic
pump from the parking brake release ports of the axle and
re-connect the hydraulic hose.

8. Repeat steps 4 to 7 for the other hydraulic connection
port (Figure 3)
9. Crawl out from under the Telehandler and clear the area
of any unnecessary personnel.
10. Carefully remove the blocking from each of the four (4)
tires and tow the vehicle to a secure location.
NEVER operate the Telehandler with the manual hydraulic
pump connected.
