INSTALLATION

Fig. 3 Lifting Shaper

LIFTING

Lift your Cincinnati Shaper with a rope Slingl Properlyplaced. The rope should bear against the COlumn, hathfront andrear as iuustrated, and not against the scrapedbearingof the ram. The ram bearing is a finely finishedsurface and must be carefully protected against damage.DO NOT USE CHAIN OR CABLE.

Adjust the sling to lift evenly. Use a Manila rope ingood condition. A 1;" rope is large enough for 24"standard and s'maller. A 2" rope should be used for24ll Heavy I)uty and larger. If Manila rope is not a-vaLilable, use Jute rope in diameters Of 2" and 2i" re-spectively. If machine is equipped with POWer downfeed to the head, remove power down feed I)racket andguard before attaching sling.

UNPACKING

Remove crate and wrapping. Unpack ram guard,wrenches, and tool post in tool box. Use the enclosedpacking list for checking all items.

aLEANING

Remove the vise from the table. Remove all covering.Thoroughly clean protective grease from an Parts Withkerosene. These parts include ram bearing} table Sup-port, bearings, on frolut of COl`lmn, Cross I.ail bearings9rocker arm, table, vise, head slide, down feed screw,dove tall in crank gear, dials a-nd indicating Plates, feedbox bear.ingJ COntrOl handles and levers, etC.

Go over the grease With a Cloth Wet With kerosene andallow to soak. Use a wftying cloth instead Of Waste. Astiff brush will get into the corners. Do not use anairhose--pressure will drive the dirt and grit into thebearing SUI.faces. After cleaning the ram, adjust itforward and remove from the ram bearing any greasethat might have collected at the wiper.

After cleaning thoroughly) wipe dry a.nd make Sure nOgrease or grit is left. Cm bearing surfaces lightly withfresh oil. clean machine periodically after installation.

FOUNDATION

E=

Fig. 4 Leveling Sharer

Remove skids and place machine on foundation. A solidconcrete foundation is desirable, but if not practicable,the Shaper may be set on a solid wcod floor and heldwith lag screws. Foundation plans are furnished witheach Shaper, showing the space required and locationof foundation bolts.

LEVELING

Level the machine with a precision level placed on topof the table and column as shown in Fig. 4. Alwayswipe both level and leveling surface clean. Level thema.chimewiththe level crosswise to the table and length-wise on the column. Be sure rail is securely clampedduring this operation.

The base is provided with three bearing points for easyleveling. The tiro front points coincide with the founda-tion bolt holes. The back point is halfway between therear foundation bolt holes. Put flat steel shims at thethree points as requiredto bring the Sha,per level withina thousandth of an inch per foot. After the machine islevel, grout under the base.

UNIVERSAL SIIAPERS VITH TABI,I SUPPORT

On universal machines equipped with an outboard tablesupport, indicate the support guide bar before packingat the corners of the base. The indicator should beclamped to the front of the table. Table bolts shouldbe drawn tight and rail securely clamped. The sup-port g`lide bar should be indicated the full length of therail. The support guide should be parallel with thetop of the rail within.001" perft. Packunder the

corners as required, to make the support level for thefull length. After machine is level,grout under the -base.

After three months of operation go over the machineand draw up screws holding the transmission cover,the rapid traverse arm, and the ram guard. After sixmonths of operation, recheck your machine for level.

OILING

Before starting the Shaper, clean return basin. Returnbasin is accessible through column door.

Fill gear transmission chamber with a high grade, non-foaming machine oil (Viscosity 220 seconds at 100 de-grees F.) according to instruction No. 1I Fig. 5.

Fill the return basin according to instruction No. 3,Fig.5.

Oil should not be below sight gauge in the base whenShaper is stopped.

Check the motor lubrication.

For complete instruction, see Fig. 5 and Oiling Dia-gram, Fig. 7.

CHANGING OIL

Change oil 30 days after installation, thereafter onceevery 12 months. \men changing oil, clean ring mag-net and wipe out return basin and main reservoir witha cloth. Do not use waste.

Once a year removeall oil from Shaper and refill with fresh oil.

BEFORE STARTnro MACIIINII

Before starting the Shaper the following four itemsmust be performed see Figure 5 and 6 for location ofoiling points.

1. Pill Transmission Reservoir until oil OVerflowsinto Return Basin. See Figure 7.

2. Lubricate motor according to motor manufacturerlSrecommendations. Do not over-lubricate.

3. After filling Transmission Reservoir, cpen columndoor and fill Ret\lm Basin and Main FLeservoir. SeeFigure 7. Fill until oil shows in sight window inbase|

4. ObservePressureGauge in column near clutch con- ^trol regularly. If gauge fa.ils to show pressure, checkoil level. Check oil filter every sk months.

OPERATION

STARTINGPut gear shift lever in neutral position and see that thestroke dial reads zero. Put feed lever in neutral. Startmotor and malre sure it is running in the proper direc-tion. Arrows on the belt and pulley guard show the cor-rect direction. Engage clutch lever with gears in neu-tral and stroke at zero. Inspect the rocker. arm andsliding block to see that they a.re getting oil. oil pres-sure gauge should lea.d 50 1bs. when clutch is engaged.

OPERATION

Refer to Fig. 8 for the following reference numbers.The stroke is adjusted by turning the shaft #8 with thecrank furnished with the machine.

The stroke adjusting shaft is self-locking. The lengthof the stroke is shown on dial #5, whether the Shaperis in motion or stopped.

The ram is unchmped by lever #6 and adjusted to therequired position by turning shaft #2. The same crank

is used for positioning the ram and for adjusting thestroke.

CAUTION: DO NOT RUN RAM BACK INTO COLtJMNWITH SLIDE SET AT AN ANGLE.

Your. Cincinnati Shaper has eight speeds as shown onthe direct reading selector plate. Four speeds are ob-tained through lever #9. Four additional speeds areobtained through the back gear control lever #7. Forsurface cutting speeds, refer to the tables on cuttingspeeds on pages 10 & ll.

The amount of feed to the table is regulated by lever#4. The automatic feed is engaged and disenga.ged bylever #3. This lever is directional, that is, it showsthe direction of the table movement, whether for feedor for power rapid traverse.

A safety clutch is provided for feed and power rapidtraverse to prevent breakage in the event the tableshould run against an obstruction.

Fig. 10 Power Rapid Traverse

Your Shaper is equipped with the most modern clutchand brake available On ShaperS today. Finger tip controlof the ram movement makes for convenience and speedboth in setup and operation. Stopping of the ram isalso greatly improved. Ctoeration remains consistentover very longpeI.iOdS Of time. No adjustment is re-quired on this electrically operated clutch and brake.

The control switch furnished is standard. You can adda duplicate control to the opposite side of the machine.You can do the same with a foot control orportablecontrol if required.

CUTTING SPEED

The c`rfuing speed on a shaper is governed by length ofthe strcke and the strokes per minute. FoI. the SaJnestrokes per minute, the cutting speed increases as thestI.Oke iS lengthened. AVOID OPERATING YOURSIIAPER ON EXCESSIVEI.Y LONG STROKE AT IIIGHSPEEDS.

Theproperchart onthese pages gives the cutting SPeedSin feet per minute for the.different strckeS Per minuteand various lengths of strokes for your shaper. Thecutting speed for a job is determined by the kind ofmaterial being cut and the type of finlsh desired.

Genera||yJ Shapers are operated too slowly. The tablebelow gives speeds for various metals.
