SERVICE INSTRUCTIONS

MT-1 SERVICE JIG USER INSTRUCTIONS
1. Place the lock on the side in the slot in the middle of the jig with the handle toward you and the yellow head to the right.

2. Close the clamp (adjust pressure with the bolt and nut above the rubberfoot if necessary).
3. Loosen the four housing bolts. We recommend using an impact wrench (Model 5003-MT-2) and the 8 MM socket
hex bit for 1/2" drive (Model 5003-MT-3).

4. Open the clamp. The upper housing half will now "pop up" about 2 inches due to the spring pressure.
5. Remove the stem to replace the handle or the entire stem. Remember to fit the handle guide and the compression
spring onto the new handle before attaching the handle to the stem.

6. The cradle and vertical bar in the right corner on the jig is an assist to get the handle loop onto the stem arm. Put
the wire loop (with the wire handle end pointing away from you) at the top of the vertical flat bar with the notch, turn
the stem onto the notch and hold it firmly onto the notch with your left hand. Take the handle and pull it with a quick
jerk, and the loop will “jump” onto the stem arm over the end knob (the wire handle loop can also be pushed onto the
stem arm knob using your two thumbs, but after 50 or so handles, it is tough going!). After attaching the wire handle 5002
to the stem, make sure the wire cable is fitted under the hook at the end of the spring to keep the wire in position.
7. When re-assembling, grease the bearing areas on the bottom housing half before putting the stem down with the yellow
cone to the right, and with the stem arm into the bottom of the housing.

8. Take the spring lever pin and push it onto the end of the spring arm about 1/8", bend the spring back and hook the
lever pin in under the “hook arm” welded on the side of the jig to hold the “spring-loaded” lever pin in position.
9. Grease the stem where the upper housing will make contact (under each stem head).

10. Pull the handle toward you, making sure the wire cable is resting in the slot on the stem. Place the handle guide in the
lower housing half.
11. Place the upper housing half in position on top of the lower housing half with the four bolts already in the holes on the
upper half.
12. Use a wide screwdriver to push in the upper part of the handle guide into the cavity in the upper housing half, while you
at the same time are holding down the upper housing half with your hand.

13. While still holding down the upper housing half, place the clamp on top of the upper housing half with the spring lever
still inbetween the housing halves.
14. Use an impact wrench and lightly spin two diagonally positioned bolts so they take the thread. Do not tighten down.
If the bolt holes do not line up, use a hammer to tap the upper housing half to correct position.

15. Remove the spring lever from in between the housing halves.
16. Turn the other bolts to make sure they take thread and then tighten town on all four bolts to 74 Nm (50ftIb).

17. Once all four bolts are tight, loosen the clamp and take out the lock for cycle test. Hold the lock and pull the handle to
make sure the stem is moving freely, and that the handle swage can be parked in all positions.
18. We also suggest that the yellow cone is repainted.

NOTE: If the arm on the stem is bent or the knob at the end of the stem arm is broken off, it is evident
that the stem has been forced backwards. This happens sometimes when the container moves
longitudinally at the same instance as the crane drops it onto the locks. The stem must then be scrapped;
it cannot be used since the stem arm also regulates the stop positions of the stem.
