Maintenance Tips

• Clean drum immediately after use: Rinse the poly drum while spinning to prevent concrete, mortar, or stucco from hardening and sticking to paddles.
• Never let material dry inside: Even thin residue reduces mixing efficiency and causes imbalance over time.
• Flush after every batch: Add water and rotate the drum to wash out sand, cement, and aggregate before it sets.
• Inspect paddles regularly: Check for wear or buildup—clean paddles ensure faster, more uniform mixing.
• Keep gearbox and motor housing clean: Wipe dust and slurry off the 1/2 HP drive system to avoid overheating and wear.
• Check drum alignment & bolts: Tighten frame and mounting points to maintain stable wheelbarrow-style operation.
• Lubricate moving joints lightly: Apply minimal grease to pivot points and dump mechanism only—avoid contaminating drum.
• Protect poly drum surface: Avoid sharp tools or aggressive scraping that can damage the molded polyethylene liner.
• Store dry & covered: Prevent corrosion on frame and preserve long-term structural stability.
