INSTRUCTIONS FOR ANEW PACER

CAUTION: READ PAGES 2 & 3 BEFORE OPERATING THIS MACHINE.

This Parts and Service Manual has been supplied to enable you to take the best possible care of your new machine. By carefully following the service instructions contained in this manual, you will be assured of the best performance with minimum maintenance of your Wolf Pacer. Corrections of major maintenance problems should be made at the factory or in the field by a qualified, factory-trained maintenance representative.

'----ON-OFF SWITCH

When your new Pacer is first put into service, allow the machine to come to room temperature. Before the machine is plugged in make sure that the Motor rotates freely and the Knife is properly set, (turn the Rotor Knob at the rear of the machinesee above). The Knife should not strike the table when Knob is rotated. Caution: The Knife is factory sharpened and ready to use on a new machine. Also check to see if the Crosshead

slides freely between the Guide Plates by unscrewing the two thumb screws (see above) on the front of the machine and removing the sharpener and turning the Rotor Knob. If the Crosshead does not slide freely see page 6 for, Adjustment of the Guides. Note: Do not oil graphite Crosshead Guides. (Heavy duty steel require lubrication.

THE ELECTRICAL CONNECTOR

The Connector Box on the Pacer is drilled for both single and three phrase cord coupling (as shown below). Wolf (as well as many other) plugs will fit by using smaller pins available from the factory. If you install connection block pins, be sure that they are tight, and that the grounding support knob on the cord is used.

Before placing three phase machines into service be positive that the motor will rotate in the direction indicated by the arrow stamped on the rear

head of the motor. To check the direction of rotation make a flash contact with the switch turned on. If the rotation is not in the correct direction, it can be reversed by reversing any two of the circuit lines.

If the motor is allowed to run in the wrong direction, the crank will unscrew and damage the machine. Single phase motors automatically turn in the proper direction.

MAINTENANCE FOR ALL MODELS

PAGES 4, 5, 6 &7

INSTALLATION

OF KNIFE

Whenever it is necessary to remove the knife 'fromthe machine, disconnect the electricity and lay machine on its side with the name plate up. Insert Knife Bolt Wrench (#1 092000), loosen the Knife Bolt (#1 064050, see #4 below) and remove the knife through

the bottom of the Footplate. It is not necessary to remove the sharpener to remove the Knife.

To replace the knife, place selvage over the sharp edge of the Knife to protect your hand and force the Knife up and back in the Knife slot. When the Knife is properly seated, tighten the Knife Bolt. The machine must be in an upright position when the Knife Bolt is tightened to prevent binding. Before sharpening; see index "When Sharpening a New Knife", for your particular series machine. Read thoroughly and follow instructions carefully.

MAINTENANCE OF KNIFE STANDARD

Maintenance of the Knife and Standard, while simple, is important to the proper functioning of the machine. After 40 running hours or as necessary depending on materials cut or at least weekly, the knife slot in the standard should be cleaned free of lint and dirt. If this is neglected the standard can

become packed, which causes heating and binding of the Knife. To clean the Standard knife slot, remove the Knife and clean the slot with the Slot Cleaner (#21 01200). Never operate the machine with worn inserts in the standard. (See page 37 for tools.

KNIFE AND CROSSHEAD ALIGNMENT

Check alignment between the knife slot, standard and crosshead whenever guides are replaced or adjusted. To do this place a new Straight Knife in the slot, and slide the Knife up over the Knife Bolt Tang (#1 at right) on the Crosshead with the Knife Bolt (#4) removed. The Knife should not bind or be set away from the tang. To adjust, if need be, slightly loosen the two 3/8" bolts at the top of the Standard (#2) and tap the Standard at its top (#3) with a hammer until you get proper alignment. When properly aligned, re-tighten bolts.

LUBRICATION

MAINTENANCE ALL MODELS CONTINUED

Lubrication of this machine is easily accomplished. Every eight hours of operation add three to five drops of a good grade of 30 weight lubricating oil to Lubricator (#1 below). Do not over lubricate. NEVER OIL GRAPHITE CROSSHEAD GUIDES. (Heavy duty steel guides require lubrication.) If oil should get on Graphite Guides, they will become gummy and stall the cutter. Should this happen, clean the guides thoroughly by flushing with Keep-M-Kieen solution. Guides or Crosshead do not have to be removed from machine during cleaning. Add oil to Crosshead wick after cleaning.

A few drops of oil should be placed on moving parts and gears periodically, or after they have been cleaned in solution. Excess oil on grinder parts collects emery and will cause faster wear and poor grinding. DO NOT OIL THE ROLLERS IN THE FOOTPLATE.

The center wick (#3 at left) should be soft and come into contact with the Crosshead Wick, when the Crosshead is at the top of the stroke. Replace the wicks if they are worn or broken. To replace wick, remove the retaining screw (#5 at left) while holding the lubricator steady with your hand. The feeder tube may now be pulled out. To take off entire oiler assembly, use an open end wrench to remove the oiler tube nut (#6 at left). This is a right hand thread.

All ball bearings in this machine are sealed, pre-lubricated bearings. If the crank bearing needs to be greased or replaced, remove Connecting Rod (see page 6, Fig. A) then remove the Bearing Locknut (#4 at left) with Pin Wrench (#1 091 060). The bearing can now be pulled from the Crank with the Crank Pin Puller (not illustrated). Use a good grade of high speed bearing grease available from the factory. Bearings should be replaced only with the bearing knockers sold from Wolf. For accessories, lubricants and tools, see page 37.

CHANGING THE

RUBBER DRIVE

Occasionally the Rubber Drive (#1 in Fig. C) on the back of the Sharpener will need replacing. This is easily accomplished. Remove the worn Rubber Tire by cutting it with a knife.

To replace the Rubber Drive, engage the starting lever (#2 in Fig. C), place the new tire in the grove and stretch it over the rim with a screw driver.

NOTE: On newer models this is one piece. Order Part No. 1217550.

CARE OF ROLLERS & RETAINERS

The Rollers and Retainers on the Footplate should be removed and cleaned regularly. An air hose is ideal for this. All dirt and lint should be removed.

Do not oil the rollers.

A clean machine will always function better. It is suggested that lint and dirt should be blown out of the machine regularly with an air hose.

Must seat in backplate slot.

Cover Plate must be removed from opening inside of sharpener housing.

REMOVAL OF THE FOLLOWER

When removing or installing the Follower (#1 at left) be sure it is properly seated in the Reversing Drive Shaft (#2). When replacing the Follower Retaining Nut (#3), turn the nut down until it is tight. Sharpener must be in up position in order to get to the Follower through the side opening. A tool is available to help remove and replace the Follower. If desired order #21 07600.

WHEN

SHARPENING A

NEW KNIFE

To engage sharpener, press starting lever down as shown in the picture on page 7, Fig. C, #2. When first sharpening a new replacement knife, depress tension button (#3 at right) for two or three strokes of the sharpener and then release the button. Allow the sharpener to make two or three additional strokes without the tension button depressed. The new knife should be ready for cutting. DEPRESS THE TENSIOI\J BUTTON ONLY WHEN SHARPENING A NEW KNIFE. A burr will result from over sharpening. It is advisable to check new knives for burrs on bottom. Remove burr with hand stone if they exist.

EMERY WHEEL APPLICATIONS

Most goods use two #1280 100 - 120 grit emery wheels.

Coarse material such as denim use two #1280000 - 80 grit emery wheels.

For all wave style and notched style blades use two #1280000 - 80 grit emery wheels.

TO ASSURE BEST PERFORMANCE USE ONLY WOLF REPLACEMENT PARTS,

KNIVES AND SHARPENING STONES.

TO CLEAN OR CHANGE THE GRII\JDING WHEELS remove the grinder belt (#3 at left). Turn spring (#5 at left) to release grinding wheel shaft assembly. Remove the grinding wheel and shaft assembly (#4) by sliding it backward out of the support arm (#2). The wheels may now be changed by removing the mounting screw and washer from the inset face of the wheel.

To clean the wheels, use the wire brush supplied with the machine and spray with Wolf'sKeep-M-Kieen emery wheel cleaner. Also, use Keep-M-Kieen to remove oil and dirt from the tension rod (#1 at left) and all the grinder head parts. Before wheels and shafts are installed back in the support arms, make sure they turn freely.

				THE QUICK CHANGE BEARINGS must
	QUICK CHANGE BEARINGS			be placed in the grinder wheel support arms
				with the locating lug out. If it is inserted with
				the lug in the wrong position, it will cause the
				grinding wheel to grind the standard instead
				of the knife. It is best to run the sharpener half
				way down the knife,and then moving it
				horizontally back and forth by hand, observe
				the clearance between the standard and
				grinding wheels before running the machine.
				When replacing the belt, be sure it is
				properly seated in the pulleys. When a new
	LOCATING LUG			belt is placed on the machine the balance of
				the grinders should be checked as directed on
			GRINDER ARM

PROPER ADJUSTMENTS

OF SHARPENER

Proper adjustment and maintenance of the sharpener gives longer and better knife service. If the sharpener doesn'toperate properly and tends to grind more on one side of the knife than the other, first check to be sure that the grinding wheels are not dirty or worn. If the parts are dirty, clean them thoroughly. Check the bottom belt (#2 on page 8} for proper tension and wear by comparing it with a new belt.

If this doesn'tremedy the situation it can be corrected by adjusting the emerys. To check the grinder adjustment, remove the cap and spring (#3 on page 8} from the tension assembly. With the machine running, operate the sharpener and observe from the rear of the machine, the position of the grinding wheels relative to the knife or standard.

To adjust the emery wheel balance of the sharpener, first back out the balance screw (#3 on page 1) and, while running the sharpener with tension cap removed, observe the location of the emery wheels in relationship to the knife. The gap between the wheel and the knife will be greater on the side of the knife farthest from the adjusting screw. Next, very slowly, 1/8 turn at a time, tighten the balancing screw. The gap on the balance spring side will slowly close. When gap on both sides of knife is same, reassemble the tension cap assembly (Fig. E). Do not tighten balance screw more than required to equalize wheel to knife gap on both sides. The emery wheel balancer can also be adjusted by examining the sharpener of the blade. If the side of the blade farthest lrom the balance adjusting screw is being ground too much, tighten the screw until an even grind on both sides is achieved. If the side of the blade closest to the adjusting screw is ground to much, the balance adjusting screw should be loosened slightly.

Note: If the sharpener doesn'toperate properly after all of the above steps have been taken, it is probable that #12711 00 Fibre

When properly set, the grinding wheels are centered with the same distance between the knife and grinding wheel on each side. If only one wheel is grinding, determine which wheel it is and then stop the machine.

Be sure to remove tension cap before attempting to adjust sharpener.
