The specificati ons in thi s manual are given as general inf ormation and ar e not binding. JET reserv es the right to effect, at any time and without prior notice, alterat ions to part s, fittings, and accessory equi pment deemed necessary f or any reason whatsoever.

Receiving

Carefully unpack the planer and any loose items from the wood crate and inspect for damage. Any damage should be reported immediately to your distribut or and shipping agent. Bef ore proceeding further, read your manual thoroughly to f amiliarize yourself with proper assembly, maintenance and safety proc edur es.

Remove the screws that hold the planer to the shipping skid. Remove the protectiv e coating from the table, bed rolls, feed rolls, cutterhead and loose items packed with the machine, including lifting handl es and motor pulley. This coati ng may be removed with a soft cloth moistened with Kerosene. Do not use acetone, gasoline or lacquer thinner for this purpose. Do not use solvents on plast ic par ts.

Use care when cleaning the

cutterhead ; th e kni ves are very sharp.

Installation & Assembly

1. There are four lifting handles (Fig. 3) on the machine. P ull the handles out f or use, push in when not in use.

2. If a sling or forklif t is used to lif t the mac hine, be sure to lif t by the handles only . See Fi g. 3. Make sure machine is kept in level position while lifting.

3. For best planing performance, locate planer on a solid, level f oundation and anchor to the floor with good quality lag screws. Do not tighten screws completely yet.

4. With machine in position, test table surface lengthwise and crosswise with machinist’s level. Place met al shims under low corners.

5. Check that all four corners are supported, then tighten l ag screws.

6. Re-test level of table surfac e in both directions and adjust if necessary.

Figure 3

Starter Box

Mount the starter box at the left side of the machine with two socket head cap screws (Fig. 4).

Figure 4

Handwheel

1. Rem ove t he nut and wash er f rom the gearbox

shaft, and pl ace the handwheel onto the shaf t (Fig. 5), making sure it is oriented so the handwheel slips over the key.

2. Place flat washer and hex nut on shaft and

tighten with wrench.

3. Mount the handle in the threaded hol e in the

handwheel, and ti ghten with a wrench placed over the flat on the handle.

Table Extension Rollers (JWP-208 only)

Mount the table extension roller s to the table using the provided hex cap screws and washers (A, Fig. 6). The rollers should be adjusted bef ore operating the planer; see Adjusting Table

Extension Rollers on page 11.

Figure 5

Extension Tables (JWP-208HH only)

1. Mount a cast iron table to the edge of the

main tabl e with t hree M8 x 25 hex c ap screws (Figure 6a). Do not f ully tighten yet.

2. The ex tension table must be leveled wit h the

main table. Place a straight edge (such as a jointed board) ac r oss both tables.

3. Insert three socket set screws with a hex

wrench, and scre w them in or out a s needed until tables are level.

4. Securely tight en the hex cap screws.

5. Mount the second extension table to the

opposite side of the planer table, using the same procedure.

Dust Collection Hood

The dust collecti on hood (Fi g. 6b) comes standard with the model JWP-208 planer, and helps maintain a clean and safe work area. It is assembled to the planer with the screws and washers as shown.

Figure 6 - JWP-208 only

Figure 6a - JWP-208HH only

IMPORTANT: Make sure all knives or knife inserts are ti ght before operating machin e. On the helical head model, verify tightness of each insert (re-torque) before using the machine for the first time.

Figure 6b

Electrical Connections

El ectrical conn ections must be

made by a qualified electrician in compliance with all relevant codes. The machine mu st be properly grounded to help prevent electrical shock and possible fat al injury.

A power plug is not provided wit h the 208 planer. You may either connect one or "hard-wire" the machine dir ectly to your el ectrical panel provided there is a disconnect near the machine. Consult the wiring diagrams on pages 32-35 for further clarific ation of wiring setup.

This machine must be grounded. Grounding provides a path of least resistance to hel p divert current away from the operator in case of electrical malfunction.

Make sure the voltage of your power supply matches the specifications on the motor plate of the machine.

Extens ion Cords

The use of ex tension cords is discouraged; try to position the machine within reach of the power source. If an extension cord becomes nece ssary, make sure the cord rating is suitable for the amperage list ed on the mac hine's motor pl ate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Figure 7

The chart i n Figure 7 shows the cor rect size cord to use based on cord l ength and m otor pl ate amp rating. If in doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord.

Adjustments

Belt and Pulleys

1. Using a straight edge, align the motor pulley

(A, Fig. 8 ) and cutterhead pulley (B, Fig. 8). The motor plate can be moved for al ignment by loosening the set screws (C, Fig. 9) in the motor plate.

Figure 8

Figure 9

2. Check bel t tensi on. Pr oper tensi on is obtai ned

when there is approx imately 1/ 4” deflection of the center span of the pulleys using light finger pressure (Fig. 10).

3. If adjustment of belt tension is necessary,

loosen one pair of hex nuts (E & F, Fig. 11) and turn the other pair to raise or lower the motor plate. Re-tighten nuts.

Table Rollers

Figure 10

Figure 11

Overview

Your planer is supplied with two table rollers (A, Fig. 12) which turn as the stock i s fed int o the planer, thus reduc ing friction. It is not possible t o give exact dimensions on the proper height setting of the table rollers because each type of wood behaves diff erently.

As a general rule, however, when planing rough stock, the table rollers should be set at high position. When planing smooth stock the rollers should be set at low position.

Figure 12

Note: When raising the roller higher above the table, the available range is from .003” to .006” See Fig. 13.

The table rollers are factory set for average planing and are par allel t o the table surfac e. If you desire to adjust the table rollers higher or lower, proceed as follows:

1. Disconnect machine from power source.

2. Lay a straight edge (B, Fig. 14) across both

rollers.

3. On one side of the table, loosen the screws

(C, Fig. 14) with a hex wrench, and turn the eccentri c shafts (D, Fig. 14) to rai se or lower the rollers.

Figure 13

4. When the proper height is achieved, tighten

screws (C, Fig. 14).

5. Adj ust the r oll ers from t he opposit e side of the

table in the same manner.

Important: Be sure that the height of front and rear rollers are the same. The table rollers must always be set parallel to the table.

Adjusting Table Extension Rollers

1. Pl ace a str aight edge ov er t he extensi on rol l er

and the table, as shown in Fig. 15, to make sure the extensi on roller and table are at the same height. If necessary, adjust the table extension roll er s as f ollows:

2. Loosen the screws and washers (A, Fig. 15)

to move the extension roller to the proper position, then retighten the screws.

3. Adjust both front and rear extension rollers in

the same manner.
