Mounting the DO35 Tow Pin onto the Tow Bar

• For Australian supplied couplings, fit tow pin to towbar using spring washer and 7/8” nut supplied and torque to 440Nm (325lbs.ft) It may be necessary to hold the tow pin in place using the supplied c-spanner.
• For American supplied couplings, fit tow pin to towbar using spring washer and 1” UNF nut supplied and torque to 530Nm (390lbs.ft) It may be necessary to hold the tow pin in place using the supplied c- spanner.

Bolting the DO35 Coupling onto the Drawbar

• Always use four new bolts to secure Coupling to Trailer. Bolt grades to be minimum M12 Class 8.8 torqued to 90Nm (66lbs.ft) or ½” Grade 5 bolts torqued to 100Nm (74lbs.ft). Use either nylon insert nuts or spring washers. DO NOT ATTEMPT TO WELD the coupling to the drawbar. The coupling must always be mounted flat on the drawbar plate.
• A drawbar weight of at least 50kg (110lb) and not exceeding 350kg (772lb) is recommended.

Use of Weight Distribution Hitches

• The DO35 can be used with load distribution hitches’ providing the coupling movement is not obstructed and the maximum downward load of 350kg (772lb) prior to tightening of bars is not exceeded. With a WDH adaptor attached to the vehicle, clearance should also be checked to ensure the trailer drawbar does not foul, particularly in tight reversing situations.
• WDH Adaptors for inproved clearance with Hayman Reese Systems Available (See Accessories)

HITCHING UP WITH THE DO35

STEP 1
Ensure the Tow Pin Cover is removed from Tow Pin.

For video instructions visit  http://cruisemaster.com.au/ videos or search on YouTube “Cruisemaster – Hitching Up with the DO35”

Step 2
The Tow Pin and Universal should be free of sand, dirt and foreign objects. Lightly lubricated to ensure premature wear is avoided.

Step 3
Set the coupling to the unlocked position. Do so by pushing down on the Red Lock Button while simultaneously pushing back the Locking slide plate towards the Red Lock Button. When in position the Lock Button will spring back and pressure will be removed from the Locking Plate. At this stage in the unlocked position the viewing port in the centre of the locking mechanism should be clear.

Step 4
Raise height of trailer so the coupling is above the vehicle Tow Pin height by adjusting Jockey Wheel or Stand.

Step 5
Align Coupling over Tow Pin by moving either vehicle or trailer, then lower coupling onto tow pin using Jockey Wheel or Stand. Ensure that the Universal is fully seated on the Tow Pin; the Tow Pin will protrude through locking plate as visible via the view port.

Step 6
Once in position Push the same Red Lock Button used in Step 3 to reset the locking plate into the locked position. The Locking Plate will slide forward into place simultaneously to the button push.

Step 7
Secure the Checklock Cap, the cap will emit an audible snap when secured correctly.

• Final stage of hitching up will look as per above.
• If you are not confident in fitting this product yourself, contact Cruisemaster to find your closest preferred service agent.

SAFETY

• Keep hands and fingers clear of coupling when attaching.
• Ensure trailer safety chains are attached whilst coupling or uncoupling.
• Do not use Tow Pin or Coupling for recovery purposes.

HANDBRAKE

• If you have a coupling with a part number ending in “-I” this indicates the model includes an “Intergrated” Handbrake
• Part numbers ending in “-R” indicates the Handbrake is “Removed”.
• Some drawbar designs will restrict the handbrake on an intergrated model, in this situation we recommend the use of a Cruisemaster remotely mounted handbrake or side mount handbrake.

MAINTENANCE

To ensure a long service life we recommend the following periodic maintenance procedures.

1. Keep the Tow Pin and Universal mating surfaces clean and lightly greased at all times.
2. Check the condition of Tow Pin O-Ring and replace if necessary (Part No. 18D-DO35-101).
3. Regularly lubricate grease points with multi-purpose lithium grease.
4. Periodic adjustment of the Slotted Nut & Pin may be required if coupling head loosens excessively and should be completed by a competent person.
5. Flush with clean water or air hose if locking mechanism does not open fully due to dirt ingress.

• Cruisemaster recommends a thorough maintenance check is conducted every 10,000 Km or 12 months.
• Please note while the DO35’s E-Coat provides superior corrosion protection it may fade with extended exposure to UV. This does not affect the operation of the DO35. To best maintain the finish of the product, we recommend covering the DO35 coupling when not in use if stored outside and exposed to direct UV.
