6. Setup and Installation

The casters are designed for side-mounting on workbenches or equipment legs. An installation template is included to assist with proper placement.

Prepare the Mounting Surface: Identify the desired mounting location on the side of your workbench or equipment leg. Ensure the surface is flat and strong enough to support the caster and load.
Drill Pilot Holes: Use the provided installation template to mark the drilling points. Carefully drill pilot holes for the mounting screws.
Fix the Plate: Align the caster's mounting plate with the drilled holes and secure it firmly using the provided screws. Ensure all screws are tightened to prevent wobbling.
Install the Casters: Attach the caster wheel assembly to the fixed plate using the bolts and nuts. Ensure all connections are secure.
Repeat for all Casters: Install all four casters following the same steps, ensuring they are evenly distributed for balanced support.

7. Operating Instructions

The HOLKIE Retractable Casters feature a simple foot pedal mechanism for engaging and disengaging mobility.

To Lift and Move the Workbench: Place your foot on the caster's pedal and step down firmly. This action will lift the workbench slightly (approximately 1/2 inch) off the ground, engaging the caster wheels and allowing you to move the workbench.
To Lower and Stabilize the Workbench: Once the workbench is in the desired position, lift the pedal with your foot. This will retract the caster wheels, lowering the workbench back onto its original legs or base, providing stability.

8. Maintenance

Regular maintenance ensures the longevity and optimal performance of your HOLKIE Retractable Casters.

Cleaning: Keep the caster wheels and swivel mechanisms free from dust, debris, and sawdust. Use a dry cloth or brush to clean regularly.
Lubrication: Periodically apply a small amount of general-purpose lubricant to the swivel bearings and wheel axles to ensure smooth operation. Avoid over-lubricating.
Fastener Check: Regularly inspect all mounting screws, bolts, and nuts. Tighten any loose fasteners to maintain stability and prevent accidents.
Wear Inspection: Check the caster wheels for signs of excessive wear, cracks, or damage. Replace casters if significant wear or damage is observed.
