INSTALLATION

Power Panel

NOTE: All guards and instruction plates are installed for your safety and information and must remain on the machine as shipped from the factory.

Unpacking

Unless otherwise specified, this machine is packaged completely assembled. The drill head(s) specified on the order are shipped already installed. The machine should be unpacked carefully by removing the packaging materials without damaging any of the machine parts.

Immediately after uncrating, check off parts received against the packing list. Also, examine for any physical signs of damage incurred during shipment. The machine is inspected before and after crating at our plant. The responsibility for filing a claim against the carrier for damages incurred during shipment rests with the receiver of the goods (FOB our factory).

The machine is held in place on its shipping skid with plastic strapping material. The machine weighs approximately 850 lbs. (380 kg.), so be sure you have sufficient equipment and manpower to handle the machine safely. Contact your Authorized Challenge Dealer to arrange for installation.

Remove the protective coating of light oil from the machined surfaces with a cleaning solvent, such as type wash. Clean all other surfaces with a solvent such as C.R.C.

Power Hookup

WARNING: DISCONNECT POWER before cleaning, lubricating, servicing, or

making adjustments not requiring power. Lock the disconnect switch in the OFF position (see Power Lockout Procedure, pg. 4).

Fuse

Ground

(fig. 2)

and wired with #10 gauge wire. Optional three phase motors are available also; 230/208 three phase, 20 amp circuit, #12 GA. wire; and 460 volt three phase, 15 amp circuit, with #14 GA. wire.

Remove the lower front cover. Remove the knockout plug on the right side of the machine. Route the power cord through the knockout hole and secure using a conduit connector. Connect wire leads to terminals as shown in fig 2 (single phase use L1 and L2 only). Connect the ground lead to the power panel as shown. Replace the front cover.

On three phase machines, check to see that the motor turns in the proper direction. Briefly turn the machine on and off then look at the belt. If it turns in the opposite direction of the arrow on top of the motor, disconnect power to the machine and switch the connection of any one wire with another. Check the rotation of the motor again to be sure it turns in the proper direction.

SETUP INSTRUCTIONS

The machine is factory wired to the customer’s specification. It is the customer’s responsibility to wire the motor for the current and voltage specified on the name plate. It is important that the line voltage specified be maintained. Failure to do so will result in improper operation of the machine (see trouble shooting section for specific problems). It may be necessary to provide a dedicated line for the machine.

The standard motor for this machine is a 208/230 single phase. This machine should be on a 30 amp circuit

F.300-B/MS-5 DRILL/JULY 2000

Starting the Machine

The power for this machine is supplied by two motors; one is for the hydraulic power pack and the other is for the spindle. The hydraulic motor drives the pump directly while the spindle motor drives the drill heads. The two motors are started and stopped simultaneously by “on” and “off” push-buttons located on the control panel (the main disconnect switch must be in the “on” position, see fig. 3). The on button has a collar guard to reduce the possibility of accidental contact. Be sure both motors are operating before trying to drill paper.

(fig. 3)

Safety Interlock System

The MS-5 paper drill is equipped with a safety interlock system which prevents the machine from being started with the front cover open or the optional drill guard removed. If the cover is opened or the guard removed when the drill is in operation, the motors will shut off and must be restarted when the cover and guard are back in place. This is a safety feature provided to prevent accidental contact with moving parts and must not be tampered with.

Hydraulic Check

Dovetail

Clamps

Scale

(reads from out-

side edge of head)

Dipstick

Cap

(fig. 4)

Check the hydraulic oil supply for the proper level. This check is made by removing the rear panel and unscrewing the dip stick located on the hydraulic tank (fig. 4). The oil level should be no higher than ½” (13 mm) up from the bottom of the dip stick to allow room for expansion of the oil when running. Recommended oils and a cross-reference chart are found in the maintenance section of this manual.

Positioning Drill Heads

Drill heads ordered with your machine have been installed at the factory. One ¼” drill is supplied as standard equipment with each head unless otherwise speci-

(fig. 5)

fied. The MS-5 handles two to five drilling heads mounted on a dovetail. Each head is independently adjustable allowing a minimum center-to-center distance of 17/8" (47.6 cm) to a maximum center-to-center distance of 15" (381 mm). NOTE: Any number of

heads (up to five) or combination of drill hole sizes can be drilled at one time. However, when using ½” (13 mm) drills, it is recommended that no more than three heads be used at the same time.

Always position heads so that the lift of paper being drilled is centered on the table. Drill heads are mounted on a dovetail and positioned by a scale mounted on the front of the dovetail (fig. 5).

To move heads: raise the front cover and release the drive belt tension by lifting the belt lever. Loosen the socket head screws holding the head to the dovetail and position the heads according to the scale (fig. 5). The dovetail scale is calibrated from the center of the table and is setup to give readings to the center of the holes. The scale is read from the outside edge of the drill heads. (Heads mounted to the right of center read the scale from the right side, heads to the left of center are read to the left of the head.) Once the heads are in the desired position, tighten the socket head screws in the dovetail.

ers (black bands) are in place before operation (fig. 7).

Drive Belt Adjusting

Lever

Drive Belt

Knurled Nut

(fig. 6)

Whenever changing head configurations or repositioning heads, reset the drill head belt tension. This is done by backing off the knurled adjusting nut (fig. 6) with the belt lever in the up position. Lower the lever and turn the knurled nut out until it is tight. Raise the lever and turn the knurled nut out an additional 1½ to 2 turns. Lower the lever and close the front cover.

Drill Installation

CAUTION: Always handle drills with

care to avoid severe lacerations. Even

dull drills are sharp enough to cause lacerations.

Insert the tapered head of the hollow drills into the spindles. Press the drills firmly into place so they do not fall out when the motor is first started. To prevent drill chips from flying out be sure that the drift hole cov-

Make sure the cutting stick blocks are in position before trying to drill paper.

Drill Removal

After use, drills may become seated making it difficult to remove them. Use the T-handled drill drift tool to free stuck drills. Uncover the drill drift hole by sliding the cover down. Insert the drill drift with the flat edge down and lift up to force the drill out of the head (fig. 7).

Stroke Adjustment (Table Height Adjustment)

Whenever installing new or resharpened drills, the table stroke and drill height must be adjusted. Turn in (clockwise) the table height adjustment to lower the table (fig. 3). Next, lift the front cover and back off the drill head adjustment on each head. Place a single sheet of paper under the drills and raise the table with the foot treadle. Gradually raise the table height by turning the table height knob out (counter clockwise) and pressing the foot treadle to check the table height. Continue to do this until the first drill cuts through the paper. Once the table height has been set, adjust the drill heads individually until all the drills now cut through the paper. When cutting full lifts, any further stroke adjustment can now be made with the table height adjustment knob.

Note: The MS-5 uses 2” and 21/2” long drills. Be sure to adjust the table stroke and/or drill height accordingly when changing from one drill length to another.

Adjusting the Stroke Speed

Drift Hole

Cover

F.300-B/MS-5 DRILL/JULY 2000

(fig. 7)

The hydraulic unit is equipped with an adjustable valve for regulating the table stroke speed (up and down travel). Maximum speed is 18 strokes per minute which is the speed used on the average run of work. Soft stocks such as mimeographs, NCR, etc., are apt to wrinkle at high speeds, and the speed should be regulated to a point where the best results are obtained. This is found mostly by “trial and error.”

This adjustment is made by turning the adjustable valve (located on the left side of the control panel) counterclockwise to reduce speed and clockwise to increase speed.

Never turn the speed control knob more than 2½ turns counterclockwise (slow speed) as the drill will not bottom and engage the return cycle. Less than one turn counterclockwise should suffice for all drilling operations. Slow speeds may also cause the drills to “burn” through the paper. If burning occurs, either increase

the vertical speed, sharpen the drills or check for proper belt tension.

Slower vertical speeds are recommended when drilling with the maximum number of heads.

Setting Up the Backgage

Filler Blocks Side Guide

Scales are provided in the table for setting up the backgage. The scales read in inches/mm and will give you the dimension from the back of the sheet to the centerline of the holes. Two magnetic filler blocks are provided if it is necessary to drill within 1" of the edge of the sheet, fig. 8. The blocks are ½” (13 mm) thick and when used, ½” (13 mm) must be subtracted from the scale reading to give the set up dimension. Example: To drill 3/4" (19 mm) from the edge of the sheet, install the filler blocks and set the backgage to 1¼” (32 mm) on the scale.

Using the Side Guide(s)

The adjustment for the location of the holes to the top or bottom edge of the sheet is provided by a sturdy side guide. The backgage has a series of threaded holes to which the side guide is attached with two threaded knobs. In addition, the side guide is slotted to fine adjust the position of the paper. When setting up drill head positions and side guides, always try to keep the paper centered on the table as much as possible.

Two side guides are provided as standard equipment so stock may be drilled to the left or right or for setting up multiple drilling sequences for more than five holes.

Drill Blocks

Place the drill blocks in the slot in the table. They are held tightly in place by pinching the drill block spring and placing it in the slot in the table at the end of the drill blocks (fig 9).

Table Scale

(fig. 8)

Spring

Drill Block

(fig. 9)

The drill blocks are removed by simply lifting them from their groove in the table. They should set flush with the table and may be shimmed if necessary. For best use and longest life, turn them end for end, top and bottom.

Emptying the Drill Chips

A large capacity chip bag attached to the rear of the machine, can be easily taken off and emptied by slipping it off the two hooks provided.

OPERATION

For EMERGENCY STOP release foot from treadle and turn main disconnect switch to “off” position.

CAUTION: NEVER REST YOUR FOOT ON THE TREADLE WITHOUT INTENDING TO BRING UP THE TABLE.

CAUTION: NEVER PUT HANDS OR FINGERS NEAR DRILL HEADS WHEN OPERATION THE MACHINE. SEVERE

LACERATIONS COULD RESULT.

Pressing the foot treadle activates the hydraulic unit bringing the table and stock up to the drills and returning back again automatically. The pedal must be released and depressed again before the next drill cycle assuring full control and allowing no repeat stroke. Releasing the pedal at any time stops the table movement and returns it to its normal down position, thus preventing costly errors.

The vertical movement of the table is actuated by the hydraulic unit. Depressing the foot treadle sets the hydraulic unit into action. Keeping your foot on the

F.300-B/MS-5 DRILL/JULY 2000

treadle allows the drills to drill through the entire lift of stock and reach the bottom of their stroke. At this point, the solenoid is de-energized and the valve released,

relieving the pressure off of the cylinder and allowing the table to return to the down position.

DRILLING TIPS

Important! To prevent the drill from overheating, always avoid drilling too slowly. The table should be brought

up as rapidly as possible allowing the drills to easily cut through the paper. Also, adjust the vertical table guide to return the table to the down position as rapidly as possible to avoid spinning the drills in the stock.

Slotted Holes - Instead of punching slotted holes for five and seven hole universal binding work, save time and cost by drilling a 1/2 inch diameter hole in place of the slot. The slot is only intended to allow the post or ring to be used in either location, and the large hole permits this.

Plastic Bindings - Drilling holes for plastic bindings, instead of punching them, is practical and saves a great deal of time, particularly on long run jobs.

Keep Drills Sharp - A dull drill is the major cause of drill breakage and production tie-ups. Usually after three hours of drilling, depending on the type of paper being processed, the drill should be sharpened. A dull drill results in poor quality work.

Keep Drills Clean - A dirty and rusty drill will not permit the free upward passage of the drill chips. Pressure built up by a clogged drill will split or break the drill. To keep it free from dirt or rust, clean the drill of all chips after each use and apply a light oil to the inside and outside. Drills should be cleaned out immediately after each use. This is particularly true if a coated or varnished stock has been drilled. On these jobs the coating on the chips frequently fuse the chips into one solid mass when the drill cools, causing breakage the next time the drill is used.

Lubricate Drills - Lubrication assists in the passage of the chips and helps avoid overheating of the drills. Use readily available stick lubricants for this purpose. Hold the end of the stick against the side of the rotating drill. Be sure to touch the cutting edge with the lubricant also. Wipe off excess oil before drilling. CARE MUST ALWAYS

BE TAKEN WHEN HANDLING DRILLS. Keep Spindle Clean - Clean out the drill spindle frequently. This will prevent any buildup in the spindle of the

drill. Set the Drills Correctly - Do not cut too deeply into the cutting block. The drill should just touch the block and

cleanly cut through the bottom sheet. During drilling, do not set the drill deeper into the block but change the position of the block frequently. Drilling deeper into the block dulls the drills quickly. Use a piece of chipboard underneath your stock. This will make handling the stock easier and will ensure that the last sheet is cut cleanly through.

Check for Drill Wobble - If spindles are badly worn or bent through misadjustment, have them replaced immediately. A wobbly or loosely held drill will break.

Check Your Drill Sharpener - The cutting edge of the sharpening bit should be inspected frequently to make certain that it is sharp and free of nicks. Never let a drill drop onto the sharpening bit. It will chip the sharpening edge. Use gentle pressure when sharpening - let the sharpening bit do the work. Check the sharpness of the drill after sharpening. The cutting edge should be razor sharp.

Just a little time and effort taken with each use of your paper drilling machine should result in trouble free operation over many years.

HOLLOW DRILL SHARPENER For fast, easy drill sharpening

CAUTION: Drills are sharp even after use. Be careful to keep edge away from your body. To prevent personal injury and/or damage to the drill, ALWAYS keep drills in protected area.

Here’s a unit that really makes drill sharpening easy. All you do is place the hollow drill in the tapered end of the drill holder, insert the unit on the cylinder, then turn two or three times...and you have a perfectly sharpened drill.

This Challenge Hollow Drill Sharpener can pay for itself many times over through longer drill life, easier, faster drilling, and less sharpening time. All sizes of drills from 1/8 to 1/2 inch in diameter can be sharpened.

The drill sharpener automatically puts just the right amount of bevel on the hollow drill for the best drilling results. It’s self centering, too, so that the center of the sharpening bit exactly meets the center of the hollow drill. The drill sharpener also has a replaceable sharpening bit.

Challenge Hollow Drill Sharpener A-4950 Extra Cutting Bit 4952

Instructions: NOTE: Always handle carefully

1. Be sure to wipe off all grease before using the sharpener.

2. Remove any paper chips from the hollow drill.

3. Place the hollow drill in the drill holder section. Insert the sharpening section, being very careful to bring the drill and cutting tool together without bumping.

NOTE: The cutting tool is made of a glass hard material and may be chipped by careless handling.

4. Turn the cutting unit clockwise, maintaining an even pressure until the hollow drill is sharpened (usually two or three turns). The cutting tool seldom requires regrinding, but when it does, the bit should be sent to the factory as regrinding must be done on a diamond wheel.
