WIRE KNOTTER ADJUSTMENT AND TIMING
I. PRELIMINARY STEPS:
Often the trouble can be found by an inspection of a few parts and items not directly associated with the knotters, but having considerable influence on them. Before making any adjustments, check the wire for tangle in the wire can, wire guides and rollers. Then inspect wire guides, rollers, gripper blocks and tongue. If they show excessive wear, replace them. Inspect the wire knives and replace if they are nicked.
If there is a problem with the knotter that is not readily seen, it is advisable to proceed with all of the following steps. The steps are divided into groups according to the function they pertain to, but should be followed in the order in which they are listed. Instructions here are given considering only one individual knotting assembly. Therefore, each knotting assembly should be checked and set at the same time for each step.
II. NEEDLE ADJUSTMENT:
With the needles even with lower rear wire guides, the wire guides should be adjusted as close to needles as possible and centered on the needle trough. Then run the needles up until the heads of the needles are above the wire dividers. The needle roller should clear the divider by not more than 1/8". See "A" Fig. 20. Continue to run needles to top dead center. The distance from the top leading edge of the wire knife to center of needle roller screw should be 4-1/2" for 16" bale chambers and 4-1/8" for 17" bale chambers. See "A" Fig. 21.
To adjust needle height, loosen nuts on needle yoke drive rod and turn rod "D" Fig. 14, right or left for desired setting.
With needles still on top dead center ,the center of needle roller should line up with center of pivot bolt on gripper tongue. See "C" Fig. 22.
NOTE: Other adjustment on needles are made with needle anchor bolts.
If needle side adjustment has been changed, be sure to recheck bottom wire guide alignment.
When installing a new needle, be sure to scrape paint off area against needle yoke.
6
Knotter drive chain must be installed as shown in Fig. 24 with chain on top of idler sprockets.
III WIRE GRIPPER:
Adjust grippers with cap screws on each side of tongue. "A" Fig. 22. Insert .115 gauge between tongue and cap screw. "B" Fig. 22. Adjust the tongue so that it just comes in contact with the gripper block. Adjust both sides of each knotter in the same way.
IV WIRE CUT TIMING:
With needles on top dead center, place a length of wire between gripper tongue and wire knife. Rotate knotter till wire is cut. The point of twister hook should be from 2:00 to 3:00 o'clock when wire is cut. See "A" Fig. 25.
NOTE: Consider front of baler 12:00 o'clock and the rear as 6:00 o'clock.
V HOOK AND WIRE HOLDER ADJUSTMENT
Set the twister hook 3-3/4" above the bale chamber. This measurement is from the tip of the hook to the top of the bale chamber. See "A" Fig. 23. The wire holder rod should clear the top of the hook 1/ 4" and just touch the twister shaft without any pressure. See "B" Fig. 23.
FEED FORK TRIP LATCH
To release latch use wrench on spring lever "B" Fig. 26. and pull roller clear of notch.
Spring tension can be increased or decreased by removing pin "C" Fig. 26, and installing or removing washers at "D" Fig. 26 as needed.
To test latch tension, place torque wrench on lever "E" Fig. 26. Latch should break at 80 to 90 ft. lbs.
PLUNGER lATCH ADJUSTMENT
Plunger latch cam "B" Fig. 27 should contact roller "A" Fig. 27 when tips of needles are 1-1/4" inside bale chamber. This adjustment is made at "A" Fig. 28. Cam lobe "C" Fig. 27 center of needle yoke roller. This adjustment is made by raising or lowering return rod bracket "C" Fig. 28 as needed. Clearance at "B" Fig. 28 should be not more than 1/2 inch from pin to spring rod guide.
Fig. 29
WIRE THREADING
Thread the wire from the left spool through the left wire guide iH, Fig. 29 in a straight line through the feeder house support #2, Fig. 29, to the right front wire guide #3, Fig. 29, then back between the rollers of the right rear wire guide #4, Fig. 29, and fasten to the reinforcing brace, #5, Fig. 29.
Thread the right spool of wire in the same manner to be picked up by the left needle. DO NOT THREAD THE NEEDLES.
Trip the knotter clutch and rotate kuotters slowly, making sure the needles have picked up the wires. Then complete the cycle and remove the wires from the reinforcing brace #5, Fig. 29. Baler will now be ready for operation.
There are various ways to load the wire into the can, but it should be kept in mind that it is very important that the wire does not become tangled in any way.
When threading wire, check rollers for wear and be sure all rollers are free. Check wire guides and upper wire guide wearing pin for wear.
PlUNGER KNIFE ADJUSTMENT
Knife guide on bottom offeed opening should be adjusted from 1/32" to 1/16" past stationary knife. Adjustment is made by two set screws on right side of bale chamber beneath feeder house.
Plunger side play may be removed by adjusting slide angle "D" Fig. 30 to steel slide "A" Fig. 30 on left side of bale chamber. Both top and bottom slide angles are adjustable with set screws "B" Fig. 30. Keep both kui ves sharp.

Fig. 31
SHEAR BOLTS The purpose of the shear bolt in the fly
wheelis to protect the machine from damage. See trouble shooting for possible cause. When the cause of shearing has been determined and eliminated, replace shear bolt.
When replacing shear bolt be sure and duplicate the original bolt by obtaining it from your Freeman dealer. It is anSAE grade two bright cap screw 1/2" NC X 5".
To replace shear bolt bushings remove set collar from pinion shaft then remove shear bolt. The flywheel may then be removed to inspect shear bolt bushings. If the bushings are chipped or broken replace them.
Fig. 32
TOP ROllER ON PLUNGER
Keep top plunger roller up to the top slide angle. To adjust the roller, loosen nut "A" and raise roller and shaft up or down as needed. Lock with nut "A".
PICKUP ADJUSTMENT
With bale chamber level, adjust lock nuts "B" Fig. 31 so pickup teeth clear ground by 1 inch. With pickup lowered as baler is used, setscrew "A" Fig. 31 may be adjusted for proper height. Adjust balance springs at outside end of pickup so that pickup may be lifted with one hand.

lUBRICATION
1. Use Freeman external gear grease on the bull gears and the drive pinions.
2. Grease the sealed bearings every 10,000 bales.
3. Grease all other bearings every 400 to 500 bales, depending upon baling conditions.
4. Check the oil level of your motor twice a day.
5. Check your motor clutch for lubrication.
6. The feed fork pivot shaft is mounted on tapered bearings and enclosed in a heavy cylinder-type carrier with a large grease well. Lubricate it through a relief-type grease fitting once each season.
7. Check for loose bolts and nuts, loose chains, when lubricating and check your needle timing.
8. Clean the air cleaner oil reservoir and refill to the oil level mark at least onee each day.
9. For balers with centralized lubrication system use only NLGI~"O" grease. Be sure grease is kept clean. Keep air out of grease lines.
10. Lubricate bull gear bearings through relief type grease fittings once each season.
At the factory, we protect your lubricating points by placing plastic caps over them. Keep in mind that you can ruin bearings by forcing dirt into them with your lubricating equipment. The first thing to do is to clean offthese points before greasing them.
