Restructure chainsaw docs: separate shared safety from model-specific content

Browse source 
New structure:
- chainsaws/index.md: Shared safety guide (PPE, critical rules, kickback
  prevention, reactive forces, emergency procedures, fuelling, chain
  maintenance, storage)
- chainsaws/husqvarna-t435.md: Model-specific (specs, starting, maintenance,
  troubleshooting, tree work section)
- chainsaws/parkside.md: Model-specific (specs, starting, maintenance,
  troubleshooting, chain tension adjustment)
- chainsaws/manuals/: PDF manuals for both saws

Benefits:
- Safety info in one authoritative place
- ~40% less duplicated content
- Cleaner model pages focused on operation
- Easier to add future chainsaws

# Husqvarna T435
Professional top-handle chainsaw for tree maintenance.
> [!danger] Top-Handle Chainsaw - Advanced Training Required
> This is a **top-handle chainsaw** designed specifically for tree surgery by trained professionals. Due to the compact handle design, there is an increased risk of losing control. **Professional arborist training is mandatory.**
> [!warning] Read Safety Guide First
> Before operating, read the [[chainsaws|Chainsaw Safety Guide]] for PPE requirements, critical safety rules, and emergency procedures.
## Specifications
| Spec | Value |
|------|-------|
| Make/Model | Husqvarna T435 |
| Engine | 35.2 cc, 2-stroke |
| Power | 1.5 kW / 2.0 HP @ 10,000 rpm |
| Idle speed | 2900 rpm |
| Weight | 3.4 kg (without bar/chain) |
| Fuel tank | 0.26 L (260 ml) |
| Chain oil tank | 0.17 L (170 ml) |

| Oil pump | Adjustable |
| Drive sprocket | 3/8" Spur 6, 1/4" Spur 8, or 0.325" Spur 7 |
| Storage location | *TBD* |
## Safety Devices
| Device | Function |
|--------|----------|
| **Chain brake** | Stops chain on kickback - engages manually (push forward) or automatically via inertia |
| **Throttle lockout** | Prevents accidental throttle activation |
| **Chain catcher** | Catches chain if it breaks or derails |
| **Vibration damping** | 3-unit system reduces hand-arm vibration |
| **Start/stop switch** | Quick engine shutoff |
## Pre-Use Checks
1. Check fuel level (correct 50:1 mix)
2. Check bar oil level
3. Inspect chain tension - should lift slightly off bar but still move freely
4. Check chain sharpness
5. Inspect bar for damage or wear
6. Check all guards and handles are secure
7. Test chain brake function (push forward to engage, pull back to release)
8. Check for fuel leaks
9. Make sure muffler is correctly attached with no damage
10. Check vibration damping units for cracks or deformation
## Starting Procedure
### Cold Start
1. Place saw on flat, stable ground
2. **Engage chain brake** (push front hand guard forward)
3. Set choke to **CHOKE** position
4. Press air purge bulb until fuel is visible
5. Hold front handle firmly, secure rear with foot or between knees
6. Pull starter rope until engine fires (1-4 pulls typically)
7. Move choke to **RUN** position
8. Pull starter rope until engine starts
9. Let warm up briefly
10. **Release chain brake** only when ready to cut
### Warm Start
1. Engage chain brake
2. Leave choke in **RUN** position (no choke needed)
3. Press air purge bulb a few times
4. Pull starter rope until engine starts
> [!warning] Starting Safety
> Never start the engine indoors - exhaust fumes are dangerous. Never start without guide bar and chain fitted - clutch can come loose.
## Tree Work
> [!danger] Professional Skills Required
> This top-handle saw is designed for use **in trees** by trained arborists only.
Tree work requirements:
- Specific professional arborist training
- Proper safety harness, ropes, and climbing equipment
- **Always secured with two anchor points** (never one)
- Never attempt to catch falling sections
- Work with a ground crew for communication and safety
For ground-level cutting, use the [[parkside|Parkside chainsaw]] instead - its rear-handle design is safer for non-aerial work.
## Shutdown Procedure
1. Release throttle and let engine idle
2. Push start/stop switch to **STOP**
3. Engage chain brake
4. Allow to cool before storage
5. Clean saw body and bar
6. Top up bar oil
## Fuelling
| Item | Specification |
|------|---------------|
| Fuel type | Unleaded petrol + 2-stroke oil |
| Mix ratio | 50:1 (2% oil) |
| Fuel tank | 0.26 L |
| Chain oil | Quality bar and chain oil |
| Oil tank | 0.17 L |
### Adjusting Chain Oil Flow
The oil pump is adjustable. Use a screwdriver on the adjustment screw:
- **Clockwise** = increase oil flow
- **Counterclockwise** = decrease oil flow
> [!warning] Stop the engine before adjusting oil pump.

## Troubleshooting
| Problem | Possible Cause | Solution |
|---------|----------------|----------|
| Won't start | Flooded | Wait 10 mins, try without choke |
| | No fuel | Refuel with correct 50:1 mix |
| | Spark plug fouled/wet | Clean and dry spark plug |
