Planer Unit Placement
Carefully lift the planer unit and place it onto the assembled stand. Ensure it is properly aligned with the mounting holes. Secure the planer unit to the stand using the provided hardware.
Starter Box
Mount the starter box in an easily accessible location on the planer stand. Connect the wiring according to the electrical diagram provided in the full manual.
Handwheel
Attach the handwheel to its designated shaft. Ensure it turns freely and engages properly with the height adjustment mechanism.
Extension Rollers
Install the extension rollers as per the instructions to support longer workpieces. Refer to the 'Adjustments' section for proper alignment.
Dust Collection Hood
Attach the dust collection hood to the planer's dust port. Connect it to a suitable dust collection system to maintain a clean and safe working environment.
Electrical Connections
Extension Cords
When using an extension cord, ensure it is of adequate gauge for the planer's power requirements and as short as possible to minimize voltage drop. Refer to the planer's specifications for recommended cord sizes.
Adjustments
Overview
Proper adjustment of the planer components is crucial for achieving accurate and smooth planing results. Follow these instructions carefully for optimal performance.
Control and Adjustments
Familiarize yourself with all control knobs, levers, and adjustment points on the planer before operation.
Pulleys and Belts
Regularly inspect pulleys and belts for wear and proper tension. Replace worn belts promptly.
Pulley Alignment
Ensure all pulleys are correctly aligned to prevent premature belt wear and ensure efficient power transmission.
Belt Tension
Adjust belt tension as needed to prevent slippage without overtightening, which can damage bearings.
Table Rollers
Two table rollers (A, Fig. 14) ease stock movement as it is fed through the planer. The height of the rollers is dependent on the type of wood being planed. When planing rough stock, set the rollers slightly high to keep the lumber from dragging along the table. Smooth lumber should be planed with the rollers set just above the plane of the table.

Image: Diagrams illustrating the adjustment of table rollers (Figure 13, 14, 15) and extension rollers (Figure 16) on the JET JWP-16OS Planer.
The two table rollers are preset at the factory at 0.004" above the table. The height adjustment range is from 0 to 0.06" (Fig. 15).
To adjust the rollers (refer to Figure 15):
- Disconnect machine from power source.
- Select a side (left or right) and lay a steel ruler or straightedge across both rollers (A).
- On the side selected, loosen the screws (B) with an Allen wrench, and turn the eccentric screw (C) (12mm hex head adjustment) to raise or lower the rollers to the desired level. Use a feeler gauge to measure the clearance between the table and the bottom of the straightedge.
- When the proper height is achieved, tighten screws (B).
Adjust the rollers from the opposite side of the table in the same manner.
Important: Measure in several places. This measurement must be consistent across the entire table.
Extension Roller
Referring to Figure 16:
Place a straight edge (A) over the extension roller (B) and the table to make sure the extension roller and table are at the same height.
Depth of Cut Adjustment
Adjust the depth of cut using the handwheel. Ensure the depth indicator is set correctly for the desired material removal.
Knife Adjustment
Proper knife adjustment is critical for a smooth finish and to prevent snipe. Follow the detailed instructions in the full manual for precise knife setting.
Removing and Replacing Knives
Refer to the full manual for safe and correct procedures for removing dull knives and installing new ones. Always use appropriate safety gear.
Table Adjustment
Ensure the planer table is flat and parallel to the cutterhead for accurate planing.
Checking Work Table Parallel to Cutterhead
Periodically check the work table's parallelism to the cutterhead using a straightedge and feeler gauges.
Adjusting Work Table Parallel to Cutterhead (Fine Adjustment)
Perform fine adjustments to the table for minor deviations from parallelism.
Adjusting Work Table Parallel to Cutterhead (Major Adjustment)
For significant adjustments, follow the major adjustment procedure outlined in the full manual.
Transmitting Rollers
Inspect and adjust transmitting rollers for proper feeding of material.
Infeed & Outfeed Roller Spring Tension Adjustment
Adjust the spring tension on the infeed and outfeed rollers to ensure consistent pressure on the workpiece.
Anti-Kickback
Verify that the anti-kickback fingers are functioning correctly to prevent workpiece kickback during operation.
Checking and Adjusting the Feed Roller Height
Ensure the feed rollers are set at the correct height for optimal material feeding.
Gearbox
Refer to the full manual for any necessary adjustments or maintenance related to the gearbox.
Operation
Table Locks
Engage the table locks before operation to prevent movement of the table during planing.
Power Feed
Select the appropriate power feed rate for the type of wood and desired finish.
Handwheel
Use the handwheel to precisely adjust the planing depth.
Depth Limiter
Set the depth limiter to prevent accidental over-planing.
Initial Startup
Before initial startup, ensure all safety checks are complete and the machine is properly assembled and adjusted. Run a test piece to verify settings.
