replacement of damaged components. Observe standard
wiring practices when replacing components.
Dielectric Grease

the factory when the crane was assembled. When servicing
electrical connections, dielectric grease must be re-applied
to these connections.
• All Deutsch Connectors
• All Valve Solenoid connections on Hydraulic valves and
Transmissions
• All Harness Connections
• RCL Module Connections (except M12 and M8
connectors)
Excluded Connections
Do not apply dielectric grease to the following connections:
• All Connections Inside the Cab
• M12 and M8 Connectors
• Pin-type Contacts
Applying Dielectric Grease to an Electrical Connector
Use the following procedure to apply dielectric grease to an
electrical connection. Grease should be applied immediately
prior to securing the connector. Ensure that grease is applied
to all terminal sockets (Figure 3-9).
1. Check the connection for moisture before application of
the grease. If moisture is found, clean or replace the
connector as necessary.
2. Screw a tip or trigger assembly on to the can of dielectric
grease if necessary.
3. Apply the grease onto socket (female) contacts.
4. Use a clean towel to remove excess grease from the
surface of the connector, and wipe grease into the
terminal sockets (Figure 3-9).
5. Ensure grease is applied to each terminal socket. The
towel with excess grease can be used to fill empty
terminal sockets (Figure 3-9).
6. Ensure grease is applied to the entire surface of the
connector’s rubber seal (Figure 3-9).
NOTE: Do not allow grease to come in contact with any
painted surface, or any other components.
7. If clean up is necessary, contact cleaner or petroleum
distillates can be used.
8. Secure the connector when complete.
DANGER
Serious burns may result from accidental grounding or
shorting circuits
Ensure battery is disconnected before performing any
maintenance on an electrical circuit.
If it is necessary to perform electrical maintenance on live
or hot circuits, remove all rings, watches, and other
jewelry before performing maintenance.
CAUTION
Never replace original wiring with wiring of a smaller size
(gauge). Fire or other damage to machine may result.
