Operation
Preparation
For safety and best results, please take the following steps before processing any workpiece on this jointer.
Only Use Natural, Good Quality Wood
Only use this jointer for natural, quality wood materials. Cracked stock, board with loose knots, plywood
and other engineered wood products can break apart and cause severe kickbacks, which can lead to
severe injuries and machine damages.
Do not use this jointer to cut treated lumber or anything that contains harmful chemicals. This will spread
wood dusts that contain such harmful chemicals.
Inspection
Carefully inspect workpiece for foreign objects. Nails, staples, rock chips and other objects embedded on
wood surface will damage the jointer. It is advised to clean a workpiece with a stiff brush to remove all
dirt and foreign objects ahead of time, especially for rough sawn or reclaimed lumber. Use metal detector
to scan for metal objects as needed.
Check Dimensions
For safety, NEVER process stock that is:
1. Shorter than 12”
2. Thinner than 1/2", or
3. Less than 2” wide.
Support Long Workpiece
Support long stock with rollers or other devices to avoid injuries. This also helps creating a smooth,
consistent finish.
Check Moisture Content
Check moisture content of the workpiece before operation. “Green wood” with moisture content over
20% will not cut properly and may jam the machine. Excessive moisture content will also cause jointer’s
unpainted surface to rust. Besides, as the workpiece dries, once-flattened surface can become fuzzy and
warped again. It is recommended to allow the workpiece to dry and stabilize before it is processed.
Warped Stock
Avoid using boards with severe warping, as they can be unstable and might cause severe kickbacks during
operation.
Glue Deposits
Glue left on the workpiece surface can dull the cutters and lower cut quality. Scrape off all glue deposits
from the workpiece before operation.
