Introduction

Outdoor power equipment is incredibly useful, but it can also be dangerous if not handled properly. Chainsaws, ride-on mowers, and other powered tools have the potential to cause serious injury if safety features aren't working correctly.

The good news? Most accidents can be prevented with simple pre-use safety checks. Taking a few minutes to inspect your equipment before each use could save you from injury, property damage, or costly repairs.

This comprehensive guide covers the essential safety checks you should perform before starting any outdoor power tool, with specific advice for Kiwi users.

Why Safety Checks Matter

Outdoor power equipment accidents happen more often than you might think. According to WorkSafe New Zealand, thousands of people are injured each year using lawnmowers, chainsaws, and similar tools.

Common Accident Causes

  • Faulty safety switches that don't stop the machine
  • Damaged guards that fail to protect users
  • Worn or damaged blades that can break or throw debris
  • Poor maintenance leading to unexpected failures
  • User error when safety features aren't working

Regular safety checks catch these issues before they cause problems.

Personal Protective Equipment (PPE)

Before even looking at the machine, ensure you have the right protective gear.

Essential PPE for Different Tools

For Chainsaws

  • Safety helmet with face shield or goggles
  • Hearing protection (ear muffs or plugs)
  • Chainsaw safety gloves with reinforced palms
  • Chainsaw safety boots with cut-resistant material
  • Chainsaw chaps or pants for leg protection

For Ride-on Mowers

  • Safety glasses or goggles
  • Hearing protection for extended use
  • Sturdy, closed-toe shoes
  • Long pants to protect legs

For Handheld Tools (Blowers, Trimmers)

  • Safety glasses or goggles
  • Hearing protection
  • Gloves for better grip and hand protection
  • Long pants and sleeves

PPE Tips

  • Replace damaged or worn PPE immediately
  • Ensure all PPE fits properly and is comfortable
  • Store PPE in a dry, accessible location
  • Check expiry dates on safety equipment

Pre-Start Visual Inspection

Start with a visual check of the entire machine before attempting to start it.

What to Look For

Engine and Fuel System

  • Fuel leaks: Check for wet spots or strong fuel smells
  • Fuel cap: Ensure it's securely fastened
  • Air filter: Should be clean and properly seated
  • Fuel lines: Look for cracks, kinks, or damage

Cutting Components

  • Blades: Check for damage, cracks, or missing parts
  • Guards: Ensure all guards are present and securely attached
  • Chain tension (chainsaws): Should have proper slack
  • Chain sharpness (chainsaws): Dull chains are dangerous

Safety Features

  • Kill switches: Test that they move freely
  • Safety levers: Check for proper operation
  • Throttle controls: Should return to idle when released
  • Brake systems: Particularly important for ride-on mowers

General Condition

  • Cables and wires: Look for fraying or damage
  • Bolts and fasteners: Ensure everything is tight
  • Handles and grips: Should be secure and undamaged
  • Warning labels: Must be present and legible

Functional Safety Tests

Once the visual inspection is complete, perform functional tests with the engine off.

Safety Switch Tests

Deadman Switches

  • Test that the machine stops when you release the control
  • For ride-on mowers: Machine should stop when you leave the seat
  • For handheld tools: Engine should die when throttle is released

Chain Brakes (Chainsaws)

  • Test the chain brake by activating it manually
  • Ensure it stops the chain quickly (within seconds)
  • Check that it resets properly

Blade Brakes (Mowers)

  • Engage the blade brake and confirm blades stop immediately
  • Test both manual and automatic brake functions

Control Tests

Throttle and Speed Controls

  • Test full range of motion
  • Ensure controls return to neutral/idle position
  • Check for smooth operation without sticking

Clutch Systems

  • Test engagement and disengagement
  • Ensure proper operation at all speeds

Starting and Running Tests

Only after passing all pre-start checks should you attempt to start the machine.

Safe Starting Procedures

General Rules

  • Start in a clear, open area away from people and obstacles
  • Keep the machine pointed away from yourself and others
  • Never start a machine that's been tipped or dropped recently
  • Use the correct starting procedure for your specific model

Chainsaw Starting

  • Place the saw on flat ground with the chain pointing away
  • Ensure the chain brake is engaged during starting
  • Start with the chain brake on, then release once running

Ride-on Mower Starting

  • Ensure you're seated properly
  • Keep feet and hands clear of moving parts
  • Test all controls before moving

Running Tests

Vibration and Noise

  • Excessive vibration indicates problems
  • Unusual noises suggest mechanical issues
  • Stop immediately if anything feels or sounds wrong

Performance Checks

  • Engine should run smoothly without excessive smoke
  • All controls should respond properly
  • Safety features should work as expected

Environmental Safety Considerations

Safety isn't just about the equipment — it's also about your surroundings.

Work Area Preparation

Clear the Area

  • Remove rocks, sticks, and other debris that could be thrown
  • Mark underground utilities before digging
