Common questions about manuals, registration, and support for this brand.
Match the model number on your jack to the manual title, such as BJTJ-Master-1000 or BJTJ-Maxi-1000. Also check the revision, as specifications and operating procedures can differ.
The documented models use 12V DC power. Follow your exact model's manual for wiring, connections and circuit protection requirements.
The documented models have a manual crank override. Follow your exact model's instructions because crank direction and brake-release procedures vary.
Ensure the folding foot can extend and retract fully without hitting the chassis, brake cables or mounting clamp. Follow the model-specific installation instructions; obstruction-related damage may not be covered by warranty.
Inspect the jack for damage and check wiring and connections as directed in the manual. The supplied manuals specify grease for tube lubrication and warn against using penetrating oil.
