Maintenance Tips

• Daily wipe-down: Clean pads, handles, and frame after each use to remove sweat and prevent upholstery wear and corrosion.
• Inspect ROC-IT motion system: Check the rocking arm mechanism for smooth movement and ensure no looseness or unusual noise.
• Lubricate pivot points: Use silicone/PTFE lubricant on joints, bushings, and guide areas to maintain fluid motion.
• Check cables & weight stack: Inspect for fraying, uneven travel, or sticking; ensure smooth 255 lb stack movement.
• Tighten hardware: Regularly verify bolts, seat adjusters, and frame connections for stability under heavy use.
• Clean grip options: Wipe pronated/neutral/supinated handles to maintain grip safety and hygiene.
• Keep guide paths dust-free: Clean internal tracks to preserve HOIST’s low-friction biomechanics.
• Floor stability check: Ensure machine is level to maintain proper movement alignment and user safety.
