Have power tool serviced by qualified repair person using identical replacement parts.
Hold by insulated gripping surfaces, secure workpiece, use safety glasses, avoid cutting nails, do not cut oversize.
Hold tool firmly, ensure blade is not contacting workpiece before switch, keep hands away from moving parts.
Use correct dust mask/respirator, take caution with toxic materials, follow supplier safety data.
Reposition shoe to utilize sharp blade portion for better cutting efficiency and blade life.
Check switch operation, lock switch for extended use, start by pulling trigger, stop by releasing trigger.
Ensure blade clamp sleeve is in released position before inserting or removing the blade.

The Makita Recipro Saw, model JR3050T, is a robust power tool designed for various cutting applications. It features a double insulation design for enhanced safety during operation.
The Recipro Saw is primarily used for cutting different materials, including wood and pipe. Its reciprocating action allows for efficient and versatile cutting in various situations. The tool is equipped with a switch trigger for controlling the motor and a lock button for continuous operation.
Adjusting the Shoe: A key feature of this saw is its adjustable shoe, which allows users to optimize blade life. When a section of the blade becomes dull, the shoe can be repositioned to expose a sharp, unused portion of the cutting edge. To adjust the shoe, the user pushes the shoe button in the "A" direction, which allows for five-way adjustment. Once the desired position is achieved, pushing the shoe button in the "B" direction secures the shoe in place. This mechanism helps to extend the overall life of the saw blade.
Switch Action: The tool is operated via a switch trigger. To start the saw, the user simply pulls the switch trigger. The speed of the tool is proportional to the pressure applied to the trigger. Releasing the switch trigger stops the tool. For continuous operation, the switch trigger can be pulled and then the lock button pushed in. To stop the tool from the locked position, the switch trigger must be pulled fully and then released. It is crucial to always ensure the switch trigger actuates properly and returns to the "OFF" position when released, and to maintain a firm grasp on the tool, especially when the switch is locked in the "ON" position.
Installing and Removing the Saw Blade: The saw blade installation and removal process is designed for user convenience. To install a blade, the blade clamp sleeve must first be in the released position. If it is in the fixed position, it needs to be rotated in the direction of the arrow until it locks into the released position. The saw blade is then inserted into the blade clamp as far as it will go. As the blade is inserted, the blade clamp sleeve rotates, fixing the saw blade in place. It is essential to ensure the blade is securely fixed and cannot be extracted by pulling. Failure to insert the blade deep enough can lead to it being ejected unexpectedly during operation, posing a serious danger.
To remove the saw blade, the blade clamp sleeve is rotated fully in the direction of the arrow. This action releases the blade and fixes the clamp sleeve in the released position. If the blade clamp sleeve does not lock into the released position after blade removal, the user should rotate it fully again to ensure it is properly secured. Before any blade installation or removal, it is critical to clean any chips or foreign matter from the blade, blade clamp, and slider to prevent insufficient tightening and potential injury.
Operation Guidelines: During operation, the shoe should always be pressed firmly against the workpiece. Holding the shoe away can cause strong vibration and twisting, potentially leading to the blade snapping. When cutting metal, it is recommended to wear gloves to protect hands from hot flying chips and to use a suitable coolant (cutting oil) to prevent premature blade wear. Eye protection conforming to national standards should always be worn. When starting a cut, the blade should be brought into light contact with the workpiece to create a pilot groove at a slower speed, then a faster speed can be used to continue cutting. The tool should not be operated at no-load unnecessarily.
General Maintenance: Before performing any inspection or maintenance, the tool must always be switched off and unplugged to prevent accidental starting.
Replacing Carbon Brushes: Regular inspection and replacement of carbon brushes are vital for the tool's longevity and performance. The carbon brushes should be checked regularly and replaced when they wear down to the limit mark. It is important to keep the carbon brushes clean and ensure they can slip freely in their holders. Both carbon brushes should be replaced simultaneously with identical carbon brushes to maintain optimal performance. To replace them, a screwdriver is used to remove the brush holder caps, the worn brushes are taken out, new ones inserted, and the caps secured.
Safety and Reliability: For maintaining the product's safety and reliability, all repairs, maintenance, or adjustments should be performed by Makita Authorized or Factory Service Centers, using only genuine Makita replacement parts. This ensures the tool continues to meet its safety standards and operates as intended.
