The Jobmate Reciprocating Saw (model 54-8150-6) is a handheld power tool designed for cutting various materials. It is equipped with a 120 V, 6.5 A motor that offers a variable speed range of 0-2500 RPM, allowing for adaptable cutting performance based on the material and application. The saw features a 1 1/8" blade stroke and weighs 8 lb (3.6 kg), making it relatively manageable for different tasks.
Function Description:
The reciprocating saw operates by moving a blade back and forth in a linear motion, making it suitable for rough cutting, demolition work, and cutting through materials like wood, metal, plastic, and drywall. Its design allows for flush cutting against surfaces and plunge cutting into materials. The tool is intended for proper use as outlined in the operating manual, emphasizing safety and adherence to specified applications.
Important Technical Specifications:
- Motor: 120 V, 6.5 A
- Variable Speed: 0-2500 RPM
- Blade Stroke: 1 1/8"
- Weight: 8 lb (3.6 kg)
- Insulation: Double insulated, equipped with a polarized plug.
Usage Features:
- Variable Speed Control: The saw features a trigger switch that allows for variable speed control. Squeezing the trigger increases the speed, providing greater control over the cutting process for different materials.
- Blade Installation and Removal: Blades are installed by loosening a blade holder set screw with a hex key, inserting the blade tang fully into the spindle, ensuring the blade passes through the pivot shoe slot, and then tightening the set screw. Blades can be installed with teeth facing either up or down, but must always face forward for cutting.
- Pivot Shoe Adjustment: The pivot shoe can be adjusted forwards and backwards. This feature allows users to utilize the entire length of the blade, expose different areas of teeth for extended blade life, or accommodate special applications requiring low clearance. The pivot shoe must always be in position during operation to prevent damage to the spindle and reciprocating mechanism.
- Ergonomic Design: The tool is designed with insulated gripping areas and a plastic handle to help prevent electrical shock and provide a secure grip during operation.
- Safety Features: The manual emphasizes several safety precautions, including wearing eye protection, using appropriate extension cords, and ensuring the workpiece is firmly anchored. It also warns against operating the tool without the pivot shoe, forcing the tool, or touching the blade/workpiece immediately after cutting due to heat.
Maintenance Features:
- General Inspection: Before each use, the tool should be inspected for damage to the circular saw, on/off switch, and cord. Users should check for damaged, missing, or worn parts, loose screws, misalignment or binding of moving parts, or any other conditions that might affect operation. Any abnormal vibration or noise should prompt immediate shutdown and correction.
- Cleaning: The tool should be unplugged from the power supply before cleaning. Compressed air is recommended as an effective cleaning method, with safety goggles always worn during this process. It is crucial to keep the handle dry, clean, and free from oil and grease, using a clean cloth for cleaning. Solvents, brake fluids, gasoline, petroleum-based products, or penetrating oil should not come into contact with plastic parts, as they can cause damage.
- Blade Maintenance: Saw blades should be kept clean and sharp. Only correct blades recommended for the type of workpiece should be used.
- Motor Vent Cleaning: When sawing materials like fiberglass, plaster, wallboard, or spackling compound, the saw motor vents should be cleaned frequently with a vacuum or compressed air to prevent abrasive materials from accelerating wear on motor bearings and brushes.
- Servicing: The tool is double insulated, and when servicing, only identical replacement parts should be used. All repairs should be performed by a qualified service technician to ensure safety and reliability.
- Cord Care: The power cord should not be abused, used to carry the tool, or pulled from an outlet. It should be kept away from heat, oil, sharp edges, or moving parts. Damaged cords must be replaced immediately.
- Storage: Idle tools should be stored out of reach of children and untrained persons.
The Jobmate Reciprocating Saw is a robust tool designed for various cutting applications, with a strong emphasis on user safety and proper maintenance to ensure longevity and reliable performance.
