Installation Instructions

5. Installation Instructions

The SAF-Holland EH-3050 E-Hitch you have purchased can be mounted 3 different ways with two load ratings. Figures 2 through 4 show the hole pattern configurations that can be used with this product.

NOTE: This product has not been

tested nor is it rated for use in a weld on application. Welding on the product will change the mechanical state of the material and cause an unsafe condition.

Failure to remove a welded EH-3050 from service will result in unexpected E-Hitch failure, which if not avoided, could result in death or serious injury.

NOTE: Mount hitch to a secure structure

with sufﬁcient strength to support load rating.

Rating 30,000 lbs. (13,608kg) (Figure 2)

Use four (4) 1/2" Grade 8 bolts with supplied hardened thick flat washers. Torque 1/2" bolts (clean and dry) to 100 ft.-lbs. (135 N•m) minimum. Nuts used must be ASTM grade “C” or better.

This hole pattern will match the following products:

b. Rotate pin counter clockwise until

the pin lock rests on top of the hitch body.

6B. Closing E-Hitch (Figure 6)

1. Position the drawbar eye in the bottom

opening of the E-Hitch. Align the eye of the drawbar under the pin.

2. To close grasp handle, lift slightly and

rotate the pin clockwise until the pin contacts the spring catch.

3. Lower the pin thru the drawbar eye,

check that the pin is fully seated.

NOTE: Be sure the drawbar size is

compatible with the coupling device on the tow vehicle. See section 3.

Operation Instructions

7. Converting Handle

The E-Hitch is packaged with the handle in the drop style position. The following instructions are for converting the hitch handle from a drop style to a fixed upright style or vice-versa.

1. If E-Hitch is not mounted securely to a vehicle the hitch frame should be gripped in a vise of adequate size to secure the Hitch while converting.

Failure to support hitch pin while changing handle could result in ejection of hitch pin, which if not avoided, may result in minor or moderate injury.

2. Pull up on handle to retract the hitch pin.

3. Place a block of wood between the hitch pin and E-Hitch frame and release the handle.

4. Remove lock nut and bolt, pull out the handle and rotate handle 180° (Figure 7).

5. Replace lock nut and bolt . Tighten lock nut to contact with pin plus 1/2 turn. Handle will now fold down towards the rear of the hitch.

6. Pull up on handle and remove block of wood placed in Step 3.

7. Check for proper operation before continued use of E-Hitch.

Maintenance Procedures

8. Maintenance Procedures

Perform the following every three months for proper performance.

• Clean and check for proper operation.

• Inspect for worn, damaged, or missing parts.

• Inspect mounting and verify it is secure.

• Correct and replace parts as required using only genuine SAF-HOLLAND replacement parts (See section 9 for spare parts).

• Using a light oil, lubricate handle pivot and internal spring (Figure 8).

• Inspect the pin contact area for wear and damage. If wear exceeds .13 in. (3 mm) from the original surface profile replace the pin (Figure 9).

• Inspect the pull force on the pin for proper spring tension. This can be done by use of a hand held force gage. Attach the gage to the handle and pull the pin up until it is approximately 1" (25 mm) above the top of the bottom flange

(Figure 10).

Maintenance Procedures

• Lower the pin until the bottom of the pin is even with the top of the bottom flange. This is done to insure there is nothing snagging on the pin to give you a false reading. When the pin bottom is level with the top of the bottom flange the force gage should read no less than 20 lbs. (89 Newtons) (Figure 11).

Regardless of the reading on the force gage if the spring is broken it must be replaced. Replacement spring part number is XA-11423-G. See section 9 for ordering information.

Failure to follow the above maintenance instructions could result in unintentional uncoupling during operation which, if not avoided, could result in death or serious injury.
